OPINION OF THE COURT
ALITO, Circuit Judge:The Southeastern Pennsylvania Transportation Authority (“SEPTA”) appeals from a judgment awarding compensatory damages to Russell Bolden, a former SEPTA maintenance custodian, based on an assertedly unconstitutional drug test that resulted in Bolden’s discharge. Bolden also appeals, contending that the district court improperly dismissed his claim for punitive damages. We will affirm the district court judgment insofar as it holds that SEPTA is liable for violating Bolden’s constitutional right against unreasonable search, but we will reverse the award of *810compensatory damages and will remand the case for a new trial on that issue. We will also affirm the dismissal of Bolden’s claim for punitive damages.
I.
Bolden was a maintenance custodian at SEPTA’s Fern Rock Depot from 1981 to 1986. In August 1986, Bolden was involved in an altercation with a SEPTA bus driver and was discharged for conduct unbecoming a SEPTA employee. Bolden’s union, the Transportation Workers’ Union Local 234 (“Local 234”), filed a grievance, which was denied by SEPTA and ultimately submitted for arbitration pursuant to the collective bargaining agreement. In June 1987, the arbitration panel ordered that Bolden be reinstated with one-half back pay.
In the meantime, SEPTA had unilaterally implemented a new drug testing policy.1 In January 1987, SEPTA promulgated Order No. 87-1, which called for random testing of certain employees. On February 3, 1987, SEPTA promulgated Order 87-2, the order at issue in this case. Order 87-2 authorized drug testing of employees returning to work after certain absences, including any disciplinary suspension or any absence of more than 30 days.2 The unions that represent SEPTA workers, including Local 234, filed an action in the Eastern District of Pennsylvania challenging the legality of SEPTA’s new policy. On February 9, 1987, the district court issued a preliminary injunction against enforcement of Order 87-1 but not Order 87-2.3 After some modification of the random-testing program, the district court held in January 1988 that this program met Fourth Amendment standards but that the return-to-work testing requirement was unconstitutional. Transport Workers’ Local 234 v. SEPTA, 678 F.Supp. 543 (E.D.Pa.1988).
We affirmed both of these holdings. Transport Workers’ Local 234 v. SEPTA, 863 F.2d 1110 (3d Cir.1988), vacated, 492 U.S. 902, 109 S.Ct. 3208, 3209, 106 L.Ed.2d 560 (1989), reaffirmed, 884 F.2d 709 (3d Cir.1989).4 With respect to return-to-work testing, we wrote (id. at 1122):
SEPTA must justify its return-to-work testing on the basis of some particularized suspicion. It has, however, failed to present any evidence that the employees returning to work present some unique risk directly related to drug or alcohol use. Thus, SEPTA has not shown that this aspect of its program is initially justified or that testing of all employees returning after an absence for whatever cause has any relationship to the articulated need for the program.
As noted above, the arbitrators’ decision requiring Bolden’s reinstatement was is*811sued in June 1987, more than six months before the district court permanently enjoined enforcement of Order 87-2. Since Bolden had missed work due to a disciplinary suspension and had been absent for more than 30 days, he was directed under-Order 87-2 to submit to a medical examination, including body fluids testing, before returning to work. Bolden underwent a two-hour medical examination during which a blood sample was taken. He also provided a urine sample in private. These samples were sent to a laboratory for testing, and the results were interpreted by SEPTA to mean that Bolden had used marijuana. Thus, in August 1987, Bolden was again discharged, this time for drug use in violation of SEPTA Order 85-1.5
Once again, Local 234 filed a grievance, represented Bolden through three levels of grievance proceedings, and requested arbitration. Prior to arbitration and after enforcement of Order 87-2 was permanently enjoined in January 1988, SEPTA and the union reached a settlement of the grievance regarding Bolden’s discharge. Under this settlement, Bolden was to receive full back pay for the second part of the discharge period, but he was required to comply with one of two options. He could 1) enter SEPTA’s Employee Assistance Program and present evidence of successful substance abuse treatment, agree to an “aftercare program,” submit to a body fluids test before returning to work, and remain subject to unannounced follow-up tests or 2) submit to a body fluids test and, if he passed, meet with a substance abuse counsellor and remain subject to unannounced follow-up testing for six months. Thus, both options required Bolden to submit to a drug test before returning to work and to remain subject to testing for a period thereafter. Bolden did not comply with either option and consequently did not resume work.
Instead, Bolden filed a complaint against SEPTA under 42 U.S.C. § 1983, alleging that SEPTA had violated his constitutional rights by subjecting him to an unreasonable search and seizure and by discharging him without a prior hearing. His complaint sought both compensatory and punitive damages. SEPTA filed an answer denying that the drug test was unconstitutional and asserting the affirmative defense of accord and satisfaction based on the settlement of the second grievance. SEPTA later filed a third-party complaint against Local 234, claiming that the union was liable for any recovery obtained by Bolden since the union had negotiated the settlement with SEPTA. Bolden, in turn, filed an amended complaint that added Local 234 as a defendant. In this amended complaint, Bolden asserted that “[i]f ... Local 234 ... had any obligation to represent plaintiff in connection with this illegal drug testing and illegal discharge, which obligation is denied by plaintiff, then Local 234 participated in a conspiracy with [SEPTA] to deprive plaintiff of his XIVth Amendment rights.” According to the amended complaint, Local 234 furthered this conspiracy by failing to file a Section 1983 action on his behalf, failing to insist on arbitration within the time required by the collective bargaining agreement, and accepting an unsatisfactory settlement.
The district court denied Bolden’s and SEPTA’s cross-motions for summary judgment on liability, holding that there were genuine issues of material fact with regard to whether the drug test was reasonable, whether Bolden had consented to the test, and whether accord and satisfaction based on the settlement could be shown. The court did, however, dismiss Bolden’s claim for punitive damages under City of Newport v. Fact Concerts, Inc., 453 U.S. 247, 101 S.Ct. 2748, 69 L.Ed.2d 616 (1981). The court also granted Local 234’s unopposed motion for summary judgment on SEPTA’s third-party complaint.
Bolden’s claims against SEPTA and Local 234 were tried before a jury for eight days in March 1990. In response to interrogatories, the jury found that SEPTA had violated Bolden’s right to be free from un*812reasonable searches and seizures and found that his damages for this violation were $285,000. The jury found that SEPTA had not violated Bolden’s right to procedural due process and that Local 234 had not violated Bolden’s constitutional rights by conspiring with SEPTA. The district court denied SEPTA’s motion for judgment notwithstanding the verdict and entered judgment in favor of Bolden for the amount of the verdict. Both SEPTA and Bolden appealed.
In the briefs filed by SEPTA before the panel argument, SEPTA contended that Bolden’s drug test was reasonable because his duties posed a substantial risk of harm to himself and others and because Bolden had consented to the test. SEPTA also relied upon the settlement it reached with Local 234 after Bolden’s discharge for drug use. Finally, SEPTA contended that the judgment for $285,000 was contrary to law, excessive, and unconscionable. Bolden argued that the district court erred in dismissing his claim for punitive damages.
A panel of this court issued a judgment reversing the district court and remanding for entry of judgment in favor of SEPTA. Bolden’s petition for rehearing was subsequently granted, and the judgment of the panel was vacated.
II.
Before turning to the arguments made by the parties in the briefs submitted prior to the initial panel argument, we first address an issue that was originally raised by the panel at oral argument, viz., whether SEPTA may be sued in federal court under Section 1983. The parties addressed this question in letter-briefs submitted after the panel argument and in supplemental briefs submitted after rehearing was granted. Relying on the Supreme Court’s reasoning in Will v. Michigan Dep’t of State Police, 491 U.S. 58, 109 S.Ct. 2304, 105 L.Ed.2d 45 (1989), SEPTA contends that it is an alter ego of the Commonwealth of Pennsylvania for Eleventh Amendment purposes and that it therefore may not be sued in federal court without its consent. SEPTA also argues that, because it is not subject to suit in federal court by virtue of the Eleventh Amendment, it is also not a “person” within the meaning of 42 U.S.C. § 1983.
Before addressing the merits of this Eleventh Amendment argument, we must consider whether we should reach this issue, since it was never raised by SEPTA at any time prior to the oral argument before the panel. We do not generally consider issues not raised by the parties (see Frank v. Colt Indus., Inc., 910 F.2d 90, 100 (3d Cir.1990)), but we are always obligated to ensure that wé have jurisdiction over the cases that come before us. Mansfield, Coldwater & Lake Michigan R.R. v. Swan, 111 U.S. 379, 382, 4 S.Ct. 510, 511, 28 L.Ed. 462 (1884). “[T]he Eleventh Amendment sufficiently partakes of the nature of a jurisdictional bar so that it need not be raised in the trial court” in order to be preserved for appeal. Edelman v. Jordan, 415 U.S. 651, 678, 94 S.Ct. 1347, 1363, 39 L.Ed.2d 662 (1974); see also Ford Motor Co. v. Department of Treasury, 323 U.S. 459, 65 S.Ct. 347, 89 L.Ed. 389 (1945). The Supreme Court has held, however, that the Eleventh Amendment defense is not “jurisdictional in the sense that it must be raised and decided by [the] Court on its own motion.” Patsy v. Florida Bd. of Regents, 457 U.S. 496, 516 n. 7, 102 S.Ct. 2557 n. 7, 73 L.Ed.2d 172 (1982). Instead, the Court has suggested that when an Eleventh Amendment question is not raised by the parties, the Court may determine whether to raise and decide the question based on what is “appropriate” in each particular ease. Id. See also Alessi v. Commonwealth of Pa. Dep’t of Pub. Welfare, 893 F.2d 1444, 1455 n. 5 (3d Cir.1990) (Becker, J., concurring and dissenting).
In light of Patsy, we conclude that it is appropriate to reach the Eleventh Amendment issue in this case. In some cases in which an Eleventh Amendment issue is not raised in the district court, a lack of relevant evidence in the district court record might impede us from deciding the issue, but this problem is not present here. As discussed in Part II.F. of this opinion, the only factual question bearing on our Eleventh Amendment analysis *813in this case concerns the percentage of SEPTA’s funds provided by the Commonwealth and other sources. While these statistics are not in the record of this case, SEPTA provided these figures to the district court in Frazier v. SEPTA, Nos. 84-2950 & 84-3004, 1990 WL 82087 (E.D.Pa. June 11, 1987), a recent case in which SEPTA claimed that it was entitled to Eleventh Amendment protection. Both parties’ in banc briefs rely on these statistics; and although Bolden was not a party in Frazier, Bolden’s counsel stated during oral argument before the in banc court that he did not object to our relying upon those same facts. Consequently, it is appropriate for the in banc court to decide the important Eleventh Amendment question that is presented in this case.
B. The case now before us is only the most recent in a long string of cases in which we have considered the Eleventh Amendment’s application to a variety of governmental and semi-governmental entities. Just two and a half years ago, sitting in banc in Fitchik v. New Jersey Transit Rail Operations, 873 F.2d 655 (3d Cir.1989), cert. denied, 493 U.S. 850, 110 S.Ct. 148, 107 L.Ed.2d 107 (1989), we held that the Eleventh Amendment did not apply to the agency created by the State of New Jersey to provide public transportation following the demise or decline of many of the privately owned railroads and bus companies serving the state. See N.J.S.A. § 27:25-1 et seq. In this case, we consider whether the Eleventh Amendment applies to the entity created by the Commonwealth of Pennsylvania to provide public transportation following the demise or decline of many of the privately owned transportation companies serving southeastern Pennsylvania. In Fitchik, we applied essentially the same mode of analysis employed in cases previously decided by this court. See Port Auth. Police Benevolent Ass’n v. Port Auth. of N.Y. and N.J., 819 F.2d 413 (3d Cir.), cert. denied, 484 U.S. 953, 108 S.Ct. 344, 98 L.Ed.2d 370 (1987); Kovats v. Rutgers, The State Univ., 822 F.2d 1303 (3d Cir.1987); Blake v. Kline, 612 F.2d 718 (3d Cir.1979), cert. denied, 447 U.S. 921, 100 S.Ct. 3011, 65 L.Ed.2d 1112 (1980); Urbano v. Board of Managers, 415 F.2d 247 (3d Cir.1969), cert. denied, 397 U.S. 948, 90 S.Ct. 967, 25 L.Ed.2d 129 (1970). Because we are sitting in banc in this case, we are not bound by these precedents in the same way that a panel would be bound. See Internal Operating Procedures 9.1. Instead, we are constrained only to the degree counselled by principles of stare deci-sis. Before discussing these prior decisions, therefore, we turn to the fundamental Eleventh Amendment principles on which they were based.
C. The Eleventh Amendment provides: The judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens of Subjects of any Foreign State.
Despite this wording, the Supreme Court has interpreted the Amendment to protect an unconsenting state from “suit in federal court by its own citizens as well as those of another state.” Pennhurst State School & Hosp. v. Halderman, 465 U.S. 89, 100, 104 S.Ct. 900, 79 L.Ed.2d 67 (1984); Edelman v. Jordan, 415 U.S. 651, 662-63, 94 S.Ct. 1347, 1355-56, 39 L.Ed.2d 662 (1974). The Supreme Court has also held that the Eleventh Amendment applies to claims asserted in federal court under 42 U.S.C. § 1983. Quern v. Jordan, 440 U.S. 332, 99 S.Ct. 1139, 59 L.Ed.2d 358 (1979).
Two additional propositions established in the Supreme Court’s Eleventh Amendment decisions are important for present purposes. First, although political subdivisions of a state, such as counties and municipalities, fall within the term “State” as used in the Fourteenth Amendment,6 political subdivisions are not “State[s]” under the Eleventh Amendment. In Lincoln County v. Luning, 133 U.S. 529, 530, 10 S.Ct. 363, 363, 33 L.Ed. 766 (1890), the Court held:
*814The Eleventh Amendment limits the jurisdiction only as to suits against a State.... [W]hile the county is territorially part of the State, yet politically it is also a corporation created by and with such powers as are given to it by the State. In this respect it is a part of the State only in that remote sense in which any city, town, or other municipal corporation may be said to be a part of the State.
See also Mt. Healthy City Bd. of Educ. v. Doyle, 429 U.S. 274, 280, 97 S.Ct. 568, 572, 50 L.Ed.2d 471 (1977).
The second important principle is that the Eleventh Amendment “bars suits in federal court ‘by private parties seeking to impose a liability which must be paid from public funds in the state treasury.’ ” Hafer v. Melo, — U.S. -, 112 S.Ct. 358, 116 L.Ed.2d 301 (1991), quoting Edelman, 415 U.S. at 663, 94 S.Ct. at 1355. In Ford Motor Co. v. Department of Treasury, 323 U.S. 459, 65 S.Ct. 347, 89 L.Ed. 389 (1945), the Court held that the Eleventh Amendment barred a tax refund suit against the Indiana governor, treasurer, and auditor, “who ‘together’ constituted the board of the Department of Treasury.” Id. at 460, 65 S.Ct. at 349. The Court held that this suit “constitute[d] an action against the State of Indiana” because the judgment sought would be “satisfied by funds in the state treasury.” Id. at 463, 65 S.Ct. at 350. In Edelman, this principle was held to apply even if the relief was labelled “equitable.”
The Supreme Court has relied on these principles in deciding whether an entity is an alter ego of a state for Eleventh Amendment purposes. In Mt. Healthy, the Court held (429 U.S. at 280-81, 97 S.Ct. at 572-73) that a local board of education was “more like a county or city than it [was] like an arm of the State" and was therefore not entitled to Eleventh Amendment protection. This conclusion rested “at least in part, upon the nature of the entity created by state law,” but the Court also considered the board’s autonomy from state control and its actual and potential sources of income (id. at 280, 97 S.Ct. at 572). The Court noted (id.) that the board was “subject to some guidance from the State Board of Education and receive[d] a significant amount of money from the State,” but that under state law it possessed “extensive powers to issue bonds and to levy taxes.”
In Lake Country Estates, Inc. v. Tahoe Regional Planning Agency, 440 U.S. 391, 99 S.Ct. 1171, 59 L.Ed.2d 401 (1979), the Court considered the status of an agency created by interstate compact to exercise land use powers in a region straddling the two states. The Court reasoned (440 U.S. at 401, 99 S.Ct. at 1177) that “[i]f an interstate compact discloses that the compacting States created an agency comparable to a county or municipality, which has no Eleventh Amendment immunity, the Amendment should not be construed to immunize such an entity.” Holding that the Amendment did not apply to the entity in question, the Court stated (id. at 401-02, 99 S.Ct. at 1177-78) that most of the governing members of the agency were appointed by local governments; that the agency was funded by counties, not the states; and that the agency’s obligations were not binding on the states (id. at 402, 99 S.Ct. at 1177). The Court observed (id. at 401, 99 S.Ct. at 1177) that the states had disclaimed any intent to confer immunity, and that the function of the agency, regulation of land use, was “traditionally a function performed by local governments” (id. at 402, 99 S.Ct. at 1177).
D. Even before Mt. Healthy and Lake Country Estates, our decisions relied on essentially the same factors as the Supreme Court did in those cases. In Urbano (415 F.2d at 250-51), we consulted the following factors set out in Krisel v. Duran, 258 F.Supp. 845, 849 (S.D.N.Y.1966), aff'd, 386 F.2d 179 (2d Cir.1967), cert. denied, 390 U.S. 1042, 88 S.Ct. 1635, 20 L.Ed.2d 303 (1968):7
* * * [L]ocal law and decisions defining the status and nature of the agency in*815volved in its relation to the sovereign are factors to be considered, but only one of a number that are of significance.
Among the other factors, no one of which is conclusive, perhaps the most important is whether, in the event plaintiff prevails, the payment of the judgment will have to be made out of the state treasury; significant here also is whether the agency has the funds or the power to satisfy the judgment. Other relevant factors are whether it has been separately incorporated; the degree of autonomy over its operations; whether it has the power to sue and be sued and to enter into contracts; whether its property is immune from state taxation, and whether the sovereign has immunized itself from responsibility for the agency’s operations.
In Blake v. Kline, 612 F.2d 718 (3d Cir.1979), cert. denied, 447 U.S. 921, 100 S.Ct. 3011, 65 L.Ed.2d 1112 (1980), we relied on Urbano in considering whether the Pennsylvania Public School Employees’ Retirement Board could successfully raise the Eleventh Amendment defense. Because we found that the district court should have permitted discovery and held a hearing before ruling on the issue, we remanded for further proceedings.8 612 F.2d at 727.
In Port Auth. Police Benevolent Assoc, v. Port Auth. of N. Y. and N.J., 819 F.2d 413 (3d Cir.1987), cert. denied, 484 U.S. 953, 108 S.Ct. 344, 98 L.Ed.2d 370 (1987), we considered whether the Port Authority enjoyed Eleventh Amendment protection. We relied on Lake Country Estates as well as the Urbano factors in finding that the Port Authority could invoke this defense. We concluded (819 F.2d at 415) that the states that created the authority intended that it be considered a state agency for Eleventh Amendment purposes. We also concluded (id. at 418) that a judgment against the Authority could affect the state treasuries, since a provision in the compact mandated state contribution to the Authority unless its revenues were “adequate to meet all expenditures.” We noted (id. at 417) that the Authority was not autonomous because the governors appointed the Authority’s commissioners and because the governors and legislatures retained substantial power over Authority actions. We also observed (id. at 418) that the Authority was exempt from state taxation. Although the Authority possessed the power to sue and be sued, this was insufficient to persuade us that the Authority was not an arm of the state.9
In Kovats v. Rutgers, the State Univ., 822 F.2d 1303 (3d Cir.1987), we found that Rutgers was not an alter ego of the state. Although the university was, in part, state-created and received “a large degree of state funding,” we noted (id. at 1312) that it was “independent” and “directed] its own actions.” Perhaps most importantly, *816we stated (id. at 1312) that Rutgers was “responsible on its own for judgments resulting from [its] actions.” We wrote (id. at 1309): “Rutgers has substantial amounts of non-state funds in both commingled and segregated accounts out of which a judgment can be paid.... Rutgers retains sole discretionary control over both its commingled and segregated accounts, subject only to audit by the state.... Thus, a judgment against Rutgers can be paid from non-state funds under Rutgers’ discretionary control.” We noted (id. at 1309) that the state might choose to increase funding of the university if the university paid a judgment that reduced the non-state funds available for its educational activities. But we distinguished Rutgers from the Port Authority since the state had no statutory obligation to provide funding to Rutgers under that circumstance. We wrote (id. at 1309): “Any increase in Rutgers’ state appropriations as a result of a judgment against Rutgers will be entirely the result of discretionary action by the state.”
In Fitchik, 873 F.2d at 659 (footnote omitted), we condensed the Urbano factors into three larger questions:10
1) Whether the money that would pay the judgment would come from the state (this includes three of the Urbano factors — whether payment will come from the state treasury, whether the agency has the money to satisfy the judgment, and whether the sovereign has immunized itself from responsibility for the agency’s debts);
2) The status of the agency under state law (this includes four factors— how state law treats the agency generally, whether the entity is separately incorporated, whether the agency can sue and be sued in its own right, and whether it is immune from state taxation);
3) What degree of autonomy the agency has.
In addition, we reiterated (id.) that the most important question was “whether any judgment would be paid from the state treasury.” Applying these factors to New Jersey Transit — an entity that, as discussed below (see Part II.F. infra), is strikingly similar to SEPTA — we concluded that the Eleventh Amendment did not apply.
E. Nothing convinces us to abandon the approach taken in Urbano, Blake, Port Auth. Police, Kovats, and Fitchik. SEPTA argues that the Supreme Court’s decision in Will v. Michigan Dep’t of State Police, supra “must be taken to alter the calculus otherwise required by \FitchikJ and like cases.” SEPTA’s In Banc Brief at 5-6. “Without necessarily concluding that state law immunity has acceded to a controlling position ...,” SEPTA asserts (id), “such an analysis must now accord far more weight to that factor.”
This interpretation of Will — a decision that “[m]ost certainly ... did not rest directly on the Eleventh Amendment” (Melo v. Hafer, — U.S. -, 112 S.Ct. 358, 116 L.Ed.2d 301 (1991)) — is patently incorrect. In Will, the Supreme Court held that a state is not a “person” within the meaning of Section 1983. The Court provided essentially three reasons for this conclusion. First, the Court relied (491 U.S. at 64-66, 109 S.Ct. at 2308-09) on the language of Section 1983 and the meaning of the word “person.” Second, the Court reasoned (491 U.S. at 66-67, 109 S.Ct. at 2309-10) that Section 1983 was enacted to provide “a federal forum to remedy many deprivations of civil liberties” and that, since an uncon-senting state could not be sued in federal court by virtue of the Eleventh Amendment, Congress could not have intended for Section 1983 to provide a claim that could be asserted against a state. Third, the Court noted (491 U.S. at 67, 109 S.Ct. at 2309) that states enjoyed sovereign immunity from suit under common law, and that Section 1983 was not intended to override “well established immunities or defenses under common law.”
No portion of this reasoning supports SEPTA’s position in this case. (For *817present purposes, it is convenient to change the order in which these reasons are discussed.) The first reason cited in Will— the language of Section 1983 and the meaning of the term “person” — is relevant only in construing Section 1983, not in determining the scope of the Eleventh Amendment. Moreover, SEPTA does not claim that it does not fall within the contemporary legal usage of the term “person.” Indeed, the “Dictionary Act” (the Act of Feb. 25, 1871 § 2, 16 Stat. 431),. which was quoted by both the Will majority (491 U.S. at 69, 109 S.Ct. at 2310) and the dissent (id. at 78, 109 S.Ct. at 2315 (Brennan, J., dissenting)), defined the term “person” as generally applying to “bodies politic and corporate,” a phrase that meant “both private and public (municipal)” corporations. Id. at 69, 109 S.Ct. at 2310. Since SEPTA is a “separate body corporate and politic” (55 Pa.Stat. Ann. § 600.303(a)), it falls squarely within this definition.
The third reason cited in Will — that Section 1983 was not intended to override well-established common law immunities— likewise does not support SEPTA’s claim that it is entitled to Eleventh Amendment immunity. Even if entities like SEPTA enjoyed sovereign immunity under common law and were likewise immune from Section 1983 claims, it would not follow that those entities would be entitled to Eleventh Amendment protection. Will concluded that “the scope of the Eleventh Amendment is a consideration” when “deciphering congressional intent as to the scope of § 1983” (491 U.S. at 66-67, 109 S.Ct. at 2309-10). It clearly would be illogical, however, to reason in the opposite direction, i.e., to rely on the scope of § 1983, a statute whose predecessor was enacted in 1871, in attempting to determine the meaning of the Eleventh Amendment, a constitutional provision adopted in 1798.
The second reason cited in Will — that Section 1983 was not intended to create a cause of action that would be barred in federal court by the Eleventh Amendment — also provides no assistance to SEPTA. Unless SEPTA can show that it is entitled to Eleventh Amendment protection, this- portion of the Will analysis has no application here; and for the reasons just discussed, Will furnishes no basis for concluding that SEPTA enjoys Eleventh Amendment protection.
SEPTA’s argument with respect to Will is essentially as follows: (1) Will recognized that Section 1983 was not meant to override common law immunities recognized in 1871; (2) SEPTA now enjoys limited sovereign immunity under the Pennsylvania Sovereign Immunity Act enacted in 1978 and amended in 1980; (3) therefore SEPTA should not be suable under Section 1983; (4) and therefore SEPTA is protected by the Eleventh Amendment. This reasoning is plainly unsound. SEPTA’s immunity under a 1978 state statute obviously reveals nothing about the intended scope of Section 1983’s predecessor, which was enacted in 1871. And even if SEPTA could not be sued under Section 1983 (like municipalities prior to Monell v. New York City Dep’t of Social Services, 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978)), it would not follow that SEPTA should be regarded as a “State” under the Eleventh Amendment (any more than a municipality was viewed as a “State” for this purpose before Monell).
Acceptance of SEPTA’s interpretation of Will would revolutionize the meaning of the Eleventh Amendment. SEPTA’s position is that the Pennsylvania Sovereign Immunity Act conferred Eleventh Amendment protection upon SEPTA. As stated in the caption of part IA of its in banc brief (at 6), SEPTA maintains: “The Pennsylvania Supreme Court and This Court Have Held That SEPTA Is a Commonwealth Agency Immune From Suit Under the Pennsylvania Sovereign Immunity Act, Which Conclusion Renders SEPTA Immune From Suit Under the Eleventh Amendment.” If this reasoning were accepted, each state legislature apparently could confer Eleventh Amendment protection on any entity it wished,, including counties and cities, by enacting a statute clothing these entities with “sovereign immunity” from suit on state claims. We are confident that Will was not intended to permit anything *818of this sort. Thus, we do not believe that Will requires any alteration in the Eleventh Amendment analysis employed in Fitchik and our earlier cases.
We note that the Supreme Court rejected a similar argument in Howlett v. Rose, 496 U.S. 356, 110 S.Ct. 2430, 110 L.Ed.2d 332 (1990), decided after Will. In Howlett, the Court made clear that federal law determines who is a “person” under § 1983, id. 110 S.Ct. at 2442, 2443-44. Additionally, in rejecting a Florida law that extended immunity from state court actions under § 1983 not only to the state and its arms, but also to municipalities, counties, and school districts otherwise subject to suit under § 1983, the Court stated {id. 110 S.Ct. at 2446-47 (citations omitted) (emphasis added)):
Congress did take common law principles into account in providing certain forms of absolute and qualified immunity and in excluding States and arms of the State from the definition of person. But as to persons that Congress subjected to liability, individual States may not exempt such persons from federal liability by relying on their own common law heritage. If we were to uphold the immunity claim in this case, every State would have the same opportunity to extend the mantle of sovereign immunity to “persons” who would otherwise be subject to § 1983 liability. States would then be free to nullify for their own people the legislative decisions that Congress has made on behalf of all the People.
The decisions of other courts of appeals in analogous cases fortify our decision to retain the mode of analysis used in our earlier cases. Most of these decisions have emphasized that the most important factor is whether any judgment would have to be paid from the state treasury, but these decisions have also considered, to varying degrees, the state law characterization of the entity, the source of funding, the degree of functional autonomy, the power of the agency to sue and be sued and to enter into contracts, immunity from state taxation, and the state’s responsibility under state law for the agency’s operations. See Puerto Rico Ports Auth. v. M/V MANHATTAN PRINCE, 897 F.2d 1 (1st Cir.1990); Stewart v. Baldwin County Bd. of Educ., 908 F.2d 1499 (11th Cir.1990); Feeney v. Port Auth. Trans-Hudson Corp., 873 F.2d 628 (2d Cir.1989), aff'd, 495 U.S. 299, 110 S.Ct. 1868, 109 L.Ed.2d 264 (1990); Mitchell v. Los Angeles Community College Dist., 861 F.2d 198 (9th Cir.), cert. denied, 490 U.S. 1081, 109 S.Ct. 2102, 104 L.Ed.2d 663 (1988); Meade v. Grubbs, 841 F.2d 1512 (10th Cir.1988); Morris v. Washington Metro. Area Transit Auth., 781 F.2d 218 (D.C.Cir.1986); Foremost Guar. Corp. v. Community Sav. & Loan, Inc., 826 F.2d 1383 (4th Cir.1987); Jensen v. State Bd. of Tax Comm’rs of the State of Ind., 763 F.2d 272 (7th Cir.1985); Greenwood v. Ross, 778 F.2d 448 (8th Cir.1985); Hall v. Medical College of Oh. at Toledo, 742 F.2d 299 (6th Cir.1984), cert. denied, 469 U.S. 1113, 105 S.Ct. 796, 83 L.Ed.2d 789 (1985). The same criteria have been employed in determining the status of various transportation authorities that are similar to SEPTA in character, although different in some details. See Feeney, supra; Sanders v. Washington Metro. Area Transit Auth., 819 F.2d 1151 (D.C.Cir.1987); Morris, supra; Feary v. Regional Transit Auth., 685 F.Supp. 137 (E.D.La.1988); Weide v. Mass Transit Admin., 628 F.Supp. 247 (D.Md.1985); Morrison-Knudsen Co. v. Mass. Bay Transp. Auth., 573 F.Supp. 698 (D.Idaho 1983).
In sum, we conclude that SEPTA’s entitlement to Eleventh Amendment protection should be decided based on Fitchik and on earlier cases. We will therefore turn to that analysis.
F. 1. Funding. As previously noted, our prior cases have held that the “most important” factor is “whether any judgment would be paid from the state treasury.” Fitchik, 873 F.2d at 659; see also Urbano, 415 F.2d at 251. In Fitchik, we found that this factor provided an “extremely strong indication that [New Jersey Transit was] not the alter ego” of the state, and this factor weighs at least as heavily against SEPTA here.
*819In Fitchik, 873 F.2d at 660 (emphasis in original), we wrote that “[t]he most striking financial detail is that NJT’s money does not come predominately from the state.” Instead, New Jersey provided “less than 33% of NJT’s operating funds” (id.). Here, the figures on which SEPTA relies show that only about 27% of its revenues came from the state government.11 The remainder came from federal and local subsidies (14%), fares (54%), and other sources (5%). Thus, this most important fact weighs more heavily against SEPTA than it did against New Jersey Transit.
In Fitchik, we also relied (873 F.2d at 661) on the fact that “New Jersey [was] under no obligation to pay NJT’s debts or reimburse NJT for judgments that it pays.” “Indeed,” we added (id.), “New Jersey has specifically disclaimed any liability for NJT’s debts.” These words apply equally to SEPTA. SEPTA has “no power ... to pledge the credit or taxing power of the Commonwealth,” its obligations may not “be deemed to be obligations of the Commonwealth,” and the Commonwealth is not “liable for the payment of principal or interest on such obligations.” 1991 Pa. Laws 26, § 1503(21); 55 Pa.Stat.Ann. § 600.303(d)(20) (1991 Supp.).
Furthermore, SEPTA, like NJT, need not “request funds from the state coffers in order to meet shortfalls caused by adverse judgments.” Fitchik, 873 F.2d at 661. Rather, SEPTA, like NJT and “like a private railroad, ... can raise revenues by raising fares” (id.). See Act 26 § 1503(9) (SEPTA’s authority to set fare and services); 55 Pa.Stat.Ann. § 600.303(d)(9) (Pur-don 1991 Supp.) (same). And like NJT (Fitchik, 873 F.2d at 661), SEPTA may purchase insurance or self-insure. Act 26, § 1503(25); 55 Pa.Stat.Ann. § 600.-303(d)(24) (Purdon 1991 Supp.).
SEPTA contends that it might be unable to make up a significant shortfall by raising fares and thus might be compelled to rely on increased state subsidies. We rejected a similar argument, however, in Fitchik, 873 F.2d at 661 and Kovats, 822 F.2d at 1309. In Fitchik, we wrote (873 F.2d at 661): “Although New Jersey might appropriate funds to NJT to meet any shortfall caused by judgments against NJT, such voluntary payments by a state do not trigger [Eleventh Amendment] immunity.” A state legislature might feel compelled as a practical matter to subsidize a variety of entities that provide necessary services, including financially pressed municipalities. Such discretionary subsidies committed in reaction to a judgment, however, would not necessarily transform the recipients into alter egos of the state.
SEPTA also relies on a new state ■ law enacted in August 1991. This law provides for the revenues from a variety of fees and taxes to be paid into a “Public Transportation Assistance Fund” and distributed among “transit entities]” in accordance with a statutory formula. Act 26, § 1314. The law also provides for the Commonwealth to make an annual appropriation for public transportation assistance in order to meet certain needs. See Act 26, §§ 1302(2)(iii) and (3), 1303(a).12 Without knowing the percentage of SEPTA’s revenues that will come from state funds under this new law, and without *820knowing how the provisions relating to annual appropriations will be interpreted and implemented, we believe that the future impact of this new law is too uncertain to be given significant weight in our present decision.
We therefore conclude that the funding factor weighs at least as strongly against SEPTA’s Eleventh Amendment argument as it did against New Jersey Transit’s argument in Fitchik.
2. Status under state law. In Fitchik, 873 F.2d at 662-63, we found that this factor weighed “slightly” in favor of NJT’s Eleventh Amendment argument, and SEPTA’S status under state law is not markedly different from that of New Jersey Transit. Both entities possess certain attributes not characteristic of an arm of a state: both have a separate corporate existence,13 the power to sue and be sued,14 and the power to enter into contracts and make purchases on their own behalf.15 Both entities also possess attributes associated with sovereignty, including exemption from state property taxation16 and certain public powers such as the power of eminent domain.17 In addition, both entities are treated like their respective states under state tort laws: NJT, like the State of New Jersey itself, is subject to the New Jersey Tort Claims Act,18 and SEPTA, like the Commonwealth of Pennsylvania, is subject to the Pennsylvania Sovereign Immunity statute.19
SEPTA differs from NJT in that SEPTA is proclaimed by statute to be “an agency and instrumentality” of the Commonwealth, but this same provision also describes SEPTA as a “separate body corporate and public.”20 On the whole, SEPTA’S status under state law is not substantially stronger than NJT’s, and this factor consequently weighs “slightly” in favor of Eleventh Amendment protection.
3. Autonomy. In Fitchik, 873 F.2d at 664, we found that this factor weighed “slightly in favor of according NJT immunity” because “the degree of control by the governor [was] fairly substantial.” We noted {id. at 663) that NJT possessed a measure of autonomy, since it was governed by its own board of directors with “significant powers,” including the exclusive power to initiate action and the power “to enter contracts, bring lawsuits, purchase and sell property, buy insurance, structure the corporation’s internal management, and set and collect fares.” On the other hand, we observed that “three of the seven board members must be members of the executive branch, and the governor may veto the board’s actions” {id. at 663).
SEPTA enjoys more autonomy. SEPTA’s board possesses all of the powers cited in Fitchik, but its actions are not subject to gubernatorial veto. Moreover, only five of the fifteen board members are appointed by state officials; all of the rest are appointed by the counties that SEPTA serves.21 Although this indicates influence on SEPTA by the counties, it is the influence of the state, not that of the counties, that is important for Eleventh Amendment purposes. Thus, the autonomy factor, which weighed “slightly” in NJT’s favor, is appreciably weaker here.
*8214. The totality of factors. Funding, the most important factor, weighs at least as strongly against SEPTA as it did against NJT. SEPTA’s status under state law is not substantially stronger than NJT’s, and SEPTA has significantly more autonomy. On balance, SEPTA’s Eleventh Amendment argument is weaker than NJT’s. Since we are not prepared to overrule Fitchik, it follows that SEPTA is not protected by the Eleventh Amendment.
G. In light of our conclusion that SEPTA lacks Eleventh Amendment protection, SEPTA’s argument that it is not a “person” under Section 1983 requires only brief discussion. As previously noted, see page 812, supra, SEPTA never raised this argument until questioned during oral argument before the panel, and we generally do not raise new issues on our own motion unless federal jurisdiction is implicated. While the question of SEPTA’s status under the Eleventh Amendment is sufficiently jurisdictional in nature to permit a court to raise the question on its own motion, the argument that SEPTA is not a “person” under Section 1983, when stripped of its Eleventh Amendment component, does not implicate federal jurisdiction unless the claim that SEPTA is a “person” was made in bad faith or was “wholly insubstantial and frivolous.” Bell v. Hood, 327 U.S. 678, 682-83, 66 S.Ct. 773, 776, 90 L.Ed. 939 (1946); Kehr Packages, Inc. v. Fidelcor, Inc., 926 F.2d 1406, 1408-09 (3d Cir.), cert. denied, — U.S. -, 111 S.Ct. 2839, 115 L.Ed.2d 1007 (1991).
Under this test, the claim that SEPTA is a “person” did not raise any jurisdictional issue. Indeed, SEPTA’s only grounds for contending that it is not a “person” are the arguments based on the Eleventh Amendment and Will that were discussed above. SEPTA does not maintain that its position finds any support in the language or legislative history of Section 1983 or in cases (other than Will) that construe that provision. Thus, it is apparent that SEPTA is a “person” under Section 1983, as our prior decisions and SEPTA itself appear to have assumed for some time. See, e.g., Davis v. Southeastern Pa. Transp. Auth., 924 F.2d 51 (3d Cir.1991) (appeal from an award of attorneys fees in a successful Section 1983 claim against SEPTA). We will therefore turn to the arguments made by the parties in their initial briefs.
III.
SEPTA contends that Bolden’s drug test was reasonable because his job posed a “substantial risk of harm to himself and others.” Brief for Appellee/Cross-Appel-lant at 22. This argument must be analyzed within the framework provided by prior drug testing cases decided by the Supreme Court and by this court.
A. In Skinner v. Railway Labor Executives Ass’n, 489 U.S. 602, 109 S.Ct. 1402, 103 L.Ed.2d 639 (1989), and Treasury Employees v. Von Raab, 489 U.S. 656, 109 S.Ct. 1384, 103 L.Ed.2d 685 (1989), the Supreme Court discussed the circumstances in which government22 may require war-rantless drug testing of employees without probable cause or reasonable suspicion of drug use. The Court wrote that “where a Fourth Amendment intrusion serves special governmental needs, beyond the normal need for law enforcement, it is necessary to balance the individual’s privacy expectations against the government’s interests to determine whether it is impractical to require a warrant or some level of individualized suspicion in the particular context.” Treasury Employees, 489 U.S. at 665-66, 109 S.Ct. at 1390-91. Applying this standard, the Court in Skinner upheld Federal Railroad Administration regulations requiring blood and urine tests of railroad employees who are involved in certain train accidents, as well as regulations permitting railroads to administer breath and urine tests to employees who violate certain safety rules. In analyzing the privacy interests of the affected employees, the Court noted (489 U.S. at 627, 109 S.Ct. at 1418) that these employees’ expectations of privacy *822were “diminished by reason of their participation in an industry that is regulated pervasively to ensure safety.” Turning to the other side of the scale, the Court observed that the government interest in testing was “compelling” because “[e]mployees subject to the tests discharge duties fraught with such risks of injury to others that even a momentary lapse of attention can have disastrous consequences. Much like persons who have routine access to dangerous nuclear power facilities, ... employees who are subject to testing under the FRA regulations can cause great human loss before any signs of impairment become noticeable to supervisors or others.” Id. 489 U.S. at 628, 109 S.Ct. at 1419.
In Treasury Employees v. Von Raab, supra, the Court upheld a Customs Service program requiring urinalysis of employees seeking transfer or promotion to positions that are directly involved in drug interdiction or that require the carrying of firearms. The Court found that employees in these positions had a diminished expectation of privacy and that the government had a “compelling interest” in conducting the tests. The Court wrote (id. 489 U.S. at 670, 109 S.Ct. at 1393) that the “national interest” in self-protection could be irreparably damaged if those charged with safeguarding it were, because of their own drug use, unsympathetic to their mission of interdicting narcotics. The Court observed (id.) that drug-using agents with interdiction responsibilities could “facilitate the importation of sizeable drug shipments or block apprehension of dangerous criminals.” With respect to employees who carry weapons, the Court stated (id. 489 U.S. at 671, 109 S.Ct. at 1393) that “the public should not bear the risk that employees who may suffer from impaired perception and judgment will be promoted to positions where they may need to employ deadly force.”
We have also previously upheld warrant-less and suspicionless testing of employees holding positions analogous to those in the Supreme Court cases. As previously noted (see page 810 and footnote 4, supra), in Transport Workers’ Union, Local 234 v. SEPTA, supra, we upheld SEPTA’s program of random testing for employees in safety-sensitive positions. In our opinion after remand by the Supreme Court, we stressed that we reached this holding “only in light of the special circumstances and extraordinarily compelling government interest involved in testing railway operating personnel who ‘can cause great human loss before any signs of impairment become noticeable to supervisors or others.’ ” 884 F.2d at 712, quoting Skinner, 489 U.S. at 628, 109 S.Ct. at 1419.
Previously, in Policemen’s Benevolent Ass ’n, Local 318 v. Washington Township, 850 F.2d 133, 135 (3d Cir.1988), cert. denied, 490 U.S. 1004, 109 S.Ct. 1637, 104 L.Ed.2d 153 (1989), we upheld a municipality’s random drug testing program for police officers. We noted (850 F.2d at 141) that “the police industry [was] probably the most highly regulated” of any in the state, and that the police officers were “members of quasi-military organizations, called upon for duty at all times, armed at almost all times, and exercising the most awesome and dangerous power that a democratic state possesses with respect to its residents — the power to use force to arrest and detain them.” See also Shoemaker v. Handel, 795 F.2d 1136 (3d Cir.1986) (upholding random testing of employees in the heavy-regulated horse racing industry).
B. In the present case, we must determine whether the drug test administered to Bolden may be justified within the framework of these precedents. Accordingly, we must balance Bolden’s legitimate privacy expectations against the special need for testing asserted by SEPTA. Unlike a determination of “reasonableness” in ordinary tort cases and some other contexts, this balancing process presents a question of law, and therefore we exercise plenary review of the district court’s determination.23
*823It is clear that compulsory, suspicionless drug testing of a person holding Bolden’s job falls outside the precedents discussed above. In all of those cases, the employees subjected to suspicionless testing were found to have diminished privacy expectations due to pervasive governmental regulation of the jobs they performed. Here, SEPTA has not shown that maintenance custodians are pervasively regulated or that they have diminished privacy expectations for any other reason.
On the other side of the scale, SEPTA’s brief asserts in passing that Bolden’s duties posed a substantial risk of harm to others, but we find no factual support in the record for this contention. SEPTA did not include maintenance custodians among the employees in “safety sensitive” positions who are covered by its random-testing program. See 863 F.2d at 1114 & n. 2. Moreover, the nature of a maintenance custodian’s work does not appear to involve any great risk of causing harm to other persons. SEPTA’s job description for a maintenance custodian lists the position’s routine duties and responsibilities as follows:
GENERAL
To be proficient in the cleaning maintenance of SEPTA locations, facilities and equipment and in the performance of related duties under the general supervision of the foreperson.
1. Assigned to travel throughout SEPTA system to clean subway-elevated and surface locations, facilities and equipment.
2. Scrapes and cleans floors, walls, walks, and all SEPTA facilities.
3. Paints various items as required, such as shop equipment, wheel rims, etc.
4. Sweeps, cleans, washes vehicle interiors, exteriors.
5. Polices premises for debris, trash and scrap. Loads into truck for removal.
The main thrust of SEPTA’s argument is not that Bolden’s duties posed a risk to others but that Bolden himself might be injured at the Fern Rock Depot if his faculties were impaired by drug use. Neither the Supreme Court nor this court has endorsed the proposition that compulsory, suspicionless drug testing may be conducted to prevent an employee from causing harm to himself, rather than to others. Acceptance of SEPTA’s argument would dramatically extend current law.
In any event, we need not and do not hold that drug testing may never be justified on this ground. For present purposes, it is enough to note that SEPTA has not shown that Bolden’s position involved any unusual degree of personal danger. Certainly the routine duties and responsibilities noted above do not suggest that his job was unusually dangerous. SEPTA does not cite any statistics regarding injuries at the Fern Rock Depot or injuries to maintenance custodians, but merely states that “accidents have occurred” at the depot and specifically mentions a single accident several years ago. SEPTA also points to several hazards at the depot, such as open pits, the partially-exposed “third rail” that supplies electricity to subway cars, and trains that enter and depart at speeds of up to eighteen miles per hour. These facts do not portray a site that is markedly more dangerous than countless other industrial or transportation facilities. Thus, we hold *824that SEPTA had no special need to subject Bolden to a drug test based on any dangers presented by his job.
IV.
SEPTA also maintains that Bolden consented to the drug test because he knowingly submitted to the test without voicing any objection and later testified that he had “no qualms” about taking the test. A search of a person is constitutional if the person freely and voluntarily consents. See Schneckloth v. Bustamonte, 412 U.S. 218, 219, 224, 93 S.Ct. 2041, 2044, 2046, 36 L.Ed.2d 854 (1973). If the party conducting the search claimed the authority to search without consent, that factor weighs against a finding of voluntary consent. See, e.g., Lo-Ji Sales, Inc. v. New York, 442 U.S. 319, 329, 99 S.Ct. 2319, 2326, 60 L.Ed.2d 920 (1979); Bumper v. North Carolina, 391 U.S. 543, 549-50, 88 S.Ct. 1788, 1792, 20 L.Ed.2d 797 (1968); United States v. Molt, 589 F.2d 1247, 1251 (3d Cir.1978). Consent to search is a question of fact to be determined from the totality of the circumstances. Id. 412 U.S. at 226, 93 S.Ct. at 2047. Therefore, in reviewing a finding of fact on consent, we must view the facts in the light most favorable to the finding. See Edwards v. City of Philadelphia, 860 F.2d 568, 571 n. 2 (3d Cir.1988); Black v. Stephens, 662 F.2d 181, 188 (3d Cir.1981), cert. denied, 455 U.S. 1008, 102 S.Ct. 1646, 71 L.Ed.2d 876 (1982).
In this case, it is not clear that SEPTA preserved the issue of consent at trial. Testimony and argument on the issue were presented, and both Bolden and SEPTA submitted proposed jury instructions on consent. However, SEPTA later submitted an amended instruction that neglected to mention consent, the court gave no instruction on consent, and the record contains no indication that SEPTA objected to this omission. Apparently the jury was left to consider the facts bearing on consent as part of its general determination regarding the reasonableness of the test.
In any event, even if the issue were preserved,24 the evidence, when viewed in the light most favorable to the verdict winner, was sufficient to support a finding that Bolden did not consent. In a portion of SEPTA’s answer to Bolden’s complaint that was read into evidence, SEPTA stated that it “required the Plaintiff to submit to a body fluids test for intoxicants and controlled substances.” SEPTA’s medical director testified that if Bolden had not undergone the test, he could not have been reinstated. SEPTA does not claim that Bolden verbally consented to the test. Instead, SEPTA relies on Bolden’s knowledge that the test would be performed, his submission to the test without voicing objection, and his subsequent testimony that he had “no qualms” about the test. In essence, SEPTA argues that Bolden’s silent submission to an otherwise unconstitutional search on pain of dismissal from employment constituted consent as a matter of law. We reject this argument.
Acceptance of SEPTA’s argument in cases involving law enforcement searches would mean that no person ordered by the police to submit to a search could claim that the search was unconstitutional unless the person refused to submit or at least voiced an objection. Caselaw does not support this position. Far from holding that silent submission to a law enforcement search constitutes voluntary consent as a matter of law, the Supreme Court has examined the totality of the circumstances even in cases in which the defendant expressed verbal consent. In United States v. Mendenhall, 446 U.S. 544, 558-59, 100 S.Ct. 1870, 1879-80, 64 L.Ed.2d 497 (1980), the defendant “was twice expressly told that she was free to decline to consent to the search, and only thereafter explicitly consented to it.” 446 U.S. at 558, 100 S.Ct. at 1879. Holding that the totality of the evidence was sufficient to support the district court’s finding of voluntary consent, the Court observed that “[although the Constitution does not require ‘proof of *825knowledge of a right to refuse as the sine qua non of an effective consent to a search, ... such knowledge was highly relevant to the determination that there had been consent.’ ” Id. at 558-59, 100 S.Ct. at 1879-80, quoting Schneckloth, 412 U.S. at 234, 93 S.Ct. at 2051. In Schneckloth, the police stopped a car and asked an occupant whether they could search the car. The occupant said, “Sure, go ahead.” 412 U.S. at 220, 93 S.Ct. at 2044. The Supreme Court held that the totality of the circumstances were sufficient to show voluntary consent. Since Mendenhall and Schneck-loth both involved defendants who expressly consented, those cases would have been very easy indeed if voluntary consent could be found as a matter of law based on silent submission to a search performed by an officer claiming the right to search without consent. The analysis undertaken in those cases plainly shows that silent submission to a law enforcement search is not enough to establish voluntary consent as a matter of law.
To be sure, cases involving consent to search by law enforcement officers should not be applied mechanically to cases like this one involving administrative searches. Consent must be determined based on the totality of the circumstances in each individual case, and circumstances relating to a law enforcement search may differ from those relating to an administrative search. To take one example, the degree of coercive authority projected by those conducting the search (see Mendenhall, 446 U.S. at 558, 100 S.Ct. at 1879), may be different.
Nevertheless, we are convinced that the totality of the circumstances in this case was sufficient to support a finding that Bolden did not voluntarily consent. Viewed in the light most favorable to the verdict, the evidence showed that Bolden submitted to drug testing without voicing any objection, not because he was truly willing to undergo the test, but because he understood that the test was compulsory and that the alternative to submission was loss of his job — perhaps permanently or until after another round of potentially lengthy grievance proceedings or litigation. Accordingly, we cannot hold that Bolden consented as a matter of law.
V.
We find greater merit in SEPTA’s reliance on the settlement it reached with Local 234 following Bolden’s discharge for drug use. As previously noted, the union filed a grievance on Bolden’s behalf pursuant to the applicable provisions of the collective bargaining agreement. SEPTA and the union eventually reached a settlement of the grievance under which Bolden was to be reinstated with back pay for the second half of the discharge period but was required to submit to a drug test before returning to work, as well as to unannounced follow-up testing for some time thereafter.25 Bolden did not personally endorse this settlement. In considering the effects of the grievance settlement, it is important to distinguish between two separate questions: (a) the res judicata or collateral estoppel effect of an arbitration award or grievance settlement with respect to a subsequent claim under 42 U.S.C. § 1983 and (b) the effect for Fourth Amendment purposes of a union’s consent to drug testing, either during the negotiation of a new collective bargaining agreement or in resolving disputes about the meaning or application of an existing agreement. We will discuss each of these questions in turn.
A. We agree with Bolden that the grievance settlement in this case did not preclude his Section 1983 claim under the doctrines of res judicata or collateral estoppel. The Supreme Court considered closely related questions in several cases and held that prior arbitration decisions did not preclude subsequent federal statutory claims.
In Alexander v. Gardner-Denver Co., 415 U.S. 36, 94 S.Ct. 1011, 39 L.Ed.2d 147 (1974), the Court held that an adverse arbitration decision did not bar a discharged employee from suing under Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e *826et seq. In Barrentine v. Arkansas-Best Freight Sys., 450 U.S. 728, 101 S.Ct. 1437, 67 L.Ed.2d 641 (1981), the Court reached the same result concerning »a claim under the Fair Labor Standards Act, 29 U.S.C. § 201 et seq. Finally, in McDonald v. City of West Branch, 466 U.S. 284, 104 S.Ct. 1799, 80 L.Ed.2d 302 (1984) — a suit, like Bolden’s, under 42 U.S.C. § 1983 — the Court held that an arbitration decisioxi did not preclude a discharged public employee from suing on the ground that the discharge violated his constitutional rights.26
Insofar as the doctrines of res judicata and collateral estoppel are concerned, the present case differs from McDonald in only one particular: in McDonald there was a prior arbitration decision whereas here there was a prior grievance settlement that Bolden did not personally endorse. For present purposes, however, we see no basis for regarding this distinction as dis-positive. Accordingly, we hold that the grievance settlement in this case did not have a res judicata or collateral estoppel effect with respect to Bolden’s Section 1983 claim.
B. While Alexander, Barrentine, and McDonald control any res judicata or collateral estoppel question in this case, they do not resolve the question whether, for Fourth Amendment purposes, a public employee union may consent to future drug testing of the employees it represents. Those cases did not involve the question whether a union could affect employees’ statutory rights by consenting to future actions proposed by an employer. In addition, none of those cases concerned Fourth Amendment rights.27 Thus, Alexander, Barrentine, and McDonald do not control the Fourth Amendment question presented by the case at hand.
In analyzing this Fourth Amendment question, we begin by noting that there are a variety of circumstances in which a third party may validly consent to a search or seizure. Such consent may be provided by an agent to whom such authority has been conferred. Stoner v. Cal, 376 U.S. 483, 489, 84 S.Ct. 889, 893, 11 L.Ed.2d 856 (1964); United States v. House, 524 F.2d 1035, 1041 (3d Cir.1975). In addition, consent may be provided by certain other third parties with substantial interests or responsibilities related to the search or seizure. These third parties include, among others, a party with common authority over the premises or item to be searched (Matlock v. United States, 415 U.S. 164, 94 S.Ct. 988, 39 L.Ed.2d 242 (1974); Frazier v. Cupp, 394 U.S. 731, 740, 89 S.Ct. 1420, 1425, 22 L.Ed.2d 684 (1969)) and employees with significant responsibilities relating to the object of the search (see 3 W. LaFave, Search and Seizure § 8.6(c) (collecting cases)). In accordance with these precedents, we believe that a union such as Bolden’s may validly consent to terms and conditions of employment, such as submission to drug testing, that implicate employees’ Fourth Amendment rights.
The authority of Bolden’s union to make binding contractual commitments regarding terms and conditions of employment is well established. Under the Pennsylvania Public Employee Relations Act (PERA), Pa. Stat. tit. 43 § 1101.606 (Purdon 1991), a union is the exclusive collective bargaining representative for all of the employees in the unit, and therefore the union, in entering into a collective bargaining agreement, may agree to terms and conditions of employment that are contractually binding on all of the employees. See Vaca v. Sipes, *827386 U.S. 171, 177, 87 S.Ct. 903, 909, 17 L.Ed.2d 842 (1967); Cohen v. Temple Univ., 299 Pa.Super. 124, 445 A.2d 179, 185 (1982).
The Supreme Court has recognized, most notably in Abood v. Detroit Board of Education, 431 U.S. 209, 97 S.Ct. 1782, 52 L.Ed.2d 261 (1977), and its progeny, that a union’s authority as exclusive bargaining agent necessarily entails some restrictions on constitutional rights that individual employees would otherwise enjoy. As the Court summarized in Teachers v. Hudson, 475 U.S. 292, 301-02, 106 S.Ct. 1066, 1073-74, 89 L.Ed.2d 232 (1986) (footnote omitted):
In Abood v. Detroit Bd. of Educ., 431 U.S. 209, 97 S.Ct. 1782, 52 L.Ed.2d 261 (1977), we recognized that requiring nonunion employees to support their collective-bargaining representative “has an impact upon their First Amendment interests,” id., at 222, 97 S.Ct. at 1793, and may well “interfere in some way with an employee’s freedom to associate for the advancement of ideas, or to refrain from doing so, as he sees fit.” Id. See also id., at 255, 97 S.Ct. at 1809 (POWELL, J., concurring in judgment). We nevertheless rejected the claim that it was unconstitutional for a public employer to designate a union as the exclusive collective-bargaining representative of its employees, and to require nonunion employees, as a condition of employment, to pay a fair share of the union’s cost of negotiating and administering a collective-bargaining agreement.
The Court has permitted such interference with First Amendment interests when necessary or reasonable “for the purpose of performing the duties of an exclusive representative of the employees in dealing with the employer on labor-management issues.” Ellis v. Railway Clerks, 466 U.S. 435, 448, 104 S.Ct. 1883, 1892, 80 L.Ed.2d 428 (1984). See also Robinson v. N.J., 741 F.2d 598, 607 (3d Cir.1984). On the other hand, the Court has not permitted such interference for other purposes, such as support for political candidates or ideological causes. Abood, 431 U.S. at 235, 97 S.Ct. at 1799; Teachers v. Hudson, 475 U.S. at 302, 106 S.Ct. at 1073. We see no reason why similar principles should not be employed in determining whether a union, in its capacity as exclusive bargaining representative, may consent to terms and conditions of employment implicating Fourth Amendment interests.
Several courts of appeals in recent years have suggested that unions, in negotiating collective bargaining agreements, may consent to drug testing or analogous searches on behalf of employees. In Jackson v. Liquid Carbonic Corp., 863 F.2d 111, 119 (1st Cir.1988), cert. denied, 490 U.S. 1107, 109 S.Ct. 3158, 104 L.Ed.2d 1021 (1989), the court observed, in discussing an employee’s rights under the Fourth Amendment and state privacy law, that “the dimensions of [the employee’s] cognizable expectation of privacy [regarding drug testing] depend to a great extent upon concessions the union made regarding working conditions during collective bargaining.” In Utility Workers of Am. v. Southern Cal. Edison, 852 F.2d 1083, 1086 (9th Cir.1988) (footnote omitted), cert. denied, 489 U.S. 1078, 109 S.Ct. 1530, 103 L.Ed.2d 835 (1989), the court wrote:
To the best of our knowledge, ... no court has held that the right to be free from drug testing is one that cannot be negotiated away, and we decline to make such a ruling here.
See also Stikes v. Chevron, USA, Inc., 914 F.2d 1265, 1270 (9th Cir.1990). Similarly, in American Postal Workers Union v. USPS, 871 F.2d 556, 567 (6th Cir.1989), the court rejected a Fourth Amendment challenge to searches of employee lockers, in part because the searches were authorized by the collective bargaining agreement.
In recent years, many employers in the private and public sectors have sought to implement drug testing programs. The National Labor Relations Board has held that drug testing is a mandatory subject of bargaining. See Johnson-Bateman Co. and Machinists, AFL-CIO, Dist. Lodge 120, 131 LRRM (BNA) 1393, 1396-98 (1989). See also General Counsel Memorandum 87-5 (September 8,1987), Guideline Memorandum Concerning Drug or Alcohol *828Testing of Employees (recommending that the NLRB take the position that drug and alcohol testing be a mandatory subject of bargaining). Cf. Consolidated Rail Corp. v. Railway Labor Executives Ass’n, 491 U.S. 299, 109 S.Ct. 2477, 105 L.Ed.2d 250 (1989) (Railway Labor Act). Through collective bargaining, a public employer and union can reach agreement on detailed factual questions (such as whether particular jobs are safety-sensitive) that may have important implications under the Fourth Amendment.28 If individual public employees may litigate such questions despite the resolution reached through collective bargaining, the utility of collective bargaining with respect to drug testing in the public sector would be greatly diminished. In sum, we conclude that a public employee union acting as exclusive bargaining agent may consent to drug testing on behalf of the employees it represents.
Such consent may be manifested in several different contexts. The simplest example occurs when a union expressly agrees to drug testing during the negotiation of a collective bargaining agreement. As previously explained, individual employees are bound by such express consent.
Essentially the same analysis applies when a collective bargaining agreement implicitly authorizes drug testing. In Consolidated Rail Corp. v. Railway Labor Executives, 491 U.S. 299, 311-12, 109 S.Ct. 2477, 2484-85, 105 L.Ed.2d 250 (1989) (citations omitted), the Supreme Court explained that a collective bargaining agreement lacking any provision expressly authorizing drug tests may nevertheless implicitly permit such tests based on “ ‘practice, usage and custom.’ ” When a collective bargaining agreement contains such implied authorization, that authorization must bind individual employees as surely as an express term.
Whether a particular collective bargaining agreement contains such implied authorization must be determined in accordance with the established procedures for interpreting collective bargaining agreements. If the agreement contains provisions specifying mandatory grievance and arbitration proceedings, those procedures must be followed and exhausted before an employee may sue under the agi cement. DelCostello v. Teamsters, 462 U.S. 151, 163, 103 S.Ct. 2281, 2289-90, 76 L.Ed.2d 476 (1983). The result of this process may be a settlement or arbitration decision that the collective bargaining agreement implicitly or explicitly permits drug testing of some or all employees. The courts must defer to this interpretation of the agreement unless the employee can show that the union has breached its duty of fair representation in agreeing to the drug testing. Chauffers, Teamsters and Helpers, Local No. 391, 494 U.S. 558, 110 S.Ct. 1339, 1344, 108 L.Ed.2d 519 (1990) (NLRA); Fouts v. Allegheny County, 64 Pa. Cm with. 441, 440 A.2d 698, 701 (1982) (PERA). In other words, if the union agrees, or if binding arbitration establishes, that the collective bargaining agreement impliedly authorizes drug testing, individual employees are bound by this interpretation unless they can show a breach of the duty of fair representation.
Here, Bolden’s union, acting as his exclusive bargaining agent,29 pressed a griev-*829anee on his behalf and eventually entered into a voluntary settlement under which Bolden was to be reinstated with partial back pay on condition that he submit to future drug testing. In effect, the union and SEPTA agreed at that time that the collective bargaining agreement permitted future drug testing of Bolden in accordance with the settlement terms. Thus, unless the union breached its duty of fair representation, this settlement had the same effect under labor law and under the Fourth Amendment as if Bolden himself had consented to such future drug testing.
Bolden, however, has neither claimed nor shown that the union breached its duty of fair representation in its handling of his second grievance. As noted earlier, the claim asserted against the union in Bolden’s amended complaint was not for breach of the duty of fair representation but for conspiring with SEPTA to violate his constitutional rights. The jury rejected this claim, and Bolden has not contested that verdict on appeal. Consequently, we conclude that Bolden was bound by the terms of the settlement and that Bolden’s rejection of reemployment on these terms cut off his right to damages for lost wages following that date. See, e.g., Ford Motor Co. v. EEOC, 458 U.S. 219, 231-32, 102 S.Ct. 3057, 3065-66, 73 L.Ed.2d 721 (1982); Bruno v. W.B. Saunders Co., 882 F.2d 760, 770 (3d Cir.1989); Carden v. Westinghouse Elec. Corp., 850 F.2d 996, 1004-05 (3d Cir.1988). Because it is impossible to determine how much of the jury verdict was based on lost wages and emotional distress occurring after this settlement, we must reverse the award of damages and remand for a new trial on this issue.
VI.
A. The final question that we must consider is whether the district court properly dismissed Bolden’s request for punitive damages.30 Like the district court, we begin our analysis with City of Newport v. Fact Concerts, Inc., 453 U.S. 247, 101 S.Ct. 2748, 69 L.Ed.2d 616 (1981), in which the Supreme Court held that municipalities are immune from punitive damages under Section 1983. In reaching this conclusion, the Court considered both the history and policy of Section 1983.
In analyzing history, the Court began by assuming, as it has in other cases, that Section 1983 should not be construed as abrogating established common law immunities unless the legislative history showed that Congress desired such a result. The Court had previously held that this assumption did not lead to the conclusion that municipalities were entirely exempt from Section 1983 claims, since by 1871 municipalities no longer enjoyed complete immunity from suit under state law. Owen v. City of Independence, 445 U.S. 622, 646-47, 100 S.Ct. 1398, 1413, 63 L.Ed.2d 673 (1980). See also Will, 491 U.S. at 67 n. 7, 109 S.Ct. at 2310 n. 7. In City of Newport, however, the Court found that while municipalities could be sued under state law when Section 1983’s predecessor was enacted, the precedents at that time “were virtually unanimous in denying [punitive] damages against a municipal corporation.” The Court therefore assumed that “ ‘Congress would have specifically so provided had it wished to abolish [this] doctrine.’ ” Id. 453 U.S. at 263, 101 S.Ct. at 2758 quoting Pierson v. Ray, 386 U.S. 547, 555, 87 S.Ct. 1213, 1218, 18 L.Ed.2d 288 (1967). The Court, however, found nothing in the legislative history of Section 1 of the 1871 Act to suggest that Congress wanted to disturb the immunity from punitive damages that municipalities had previously enjoyed. 453 U.S. at 263-66, 101 S.Ct. at 2757-59.
The Court then examined “whether considerations of public policy dictate[d] a contrary result.” Id. at 266, 101 S.Ct. at 2759. Noting that a major purpose of punitive damages is to punish wrongdoers, the Court concluded that assessing punitive *830damages against a municipality would not serve this purpose because those damages would not be paid by the officials responsible for the wrongdoing but would be “visited upon the shoulders of blameless or unknowing taxpayers.” Id. at 267, 101 S.Ct. at 2760. The Court also questioned whether punitive damages were necessary to deter future violations. Id. at 268-69, 101 S.Ct. at 2760-61. The Court observed that other means of deterring constitutional violations by municipal officials were already available, such as punitive damage awards against the offending officials themselves and the discharge or electoral defeat of officials whose violations result in compensatory damage awards that must be paid with municipal funds. Id. at 268-70, 101 S.Ct. at 2760-61. Finally, the Court noted that juries traditionally have had broad discretion in assessing the amount of punitive damages and that evidence of a municipality’s large revenues might encourage sizeable awards. Id. at 270, 101 S.Ct. at 2761. The Court wrote (id. at 270-71, 101 S.Ct. at 2761-62) that “[t]he impact of such a windfall recovery is likely to be both unpredictable and, at times, substantial, and we are sensitive to the possible strain on local treasuries and therefore on services available to the public at large.”
B. Based on the Supreme Court’s reasoning in City of Newport, we conclude that SEPTA, like a municipality, is immune from punitive damages under Section 1983. In view of the many characteristics that SEPTA shares with federal, state, and local agencies, both history and policy considerations support this conclusion.
History cannot provide the same sort of specific guidance in this case as it did in City of Newport because SEPTA, unlike municipalities, is a distinctively twentieth century creation. It is doubtful that any closely comparable entities existed in 1871. Thus we cannot examine court decisions from that era addressing the immunities of such entities.
History does reveal, however, that during that era all governmental units, whether performing governmental or proprietary functions, were generally immune from punitive damages. As noted in City of Newport, municipalities and counties enjoyed such immunity, even when performing “proprietary” functions. See Genty v. Resolution Trust Corp., 937 F.2d 899, 910 (1991). In addition, both states (see Will v. Michigan Dep’t of State Police, 491 U.S. at 67, 109 S.Ct. at 2309) and the federal government (see Feres v. United States, 340 U.S. 135, 139-40, 71 S.Ct. 153, 156, 95 L.Ed. 152 (1950)), enjoyed complete sovereign immunity from suit without their consent.
SEPTA, of course, is not a governmental unit in the traditional sense, but it shares many characteristics with federal, state, and local government agencies. SEPTA is perhaps best described as a hybrid entity with substantial connections to government at all levels — federal, state, and local. While SEPTA’s ties to state government are not close enough or exclusive enough to persuade us that SEPTA should be regarded as an alter ego of the Commonwealth for Eleventh Amendment purposes, SEPTA’s ties to all levels of government taken together are sufficient to convince us that SEPTA may be analogized to a government entity for purposes of determining whether SEPTA should be liable for punitive damages. Thus, the immunity from punitive damages enjoyed by all levels of government in 1871 weighs in SEPTA’s favor here.31
Moreover, here as in City of Newport (453 U.S. at 266, 101 S.Ct. at 2759), “considerations of public policy” do not “dictate a contrary result.” The thrust of the Court’s discussion in City of Newport was that punitive damage awards against municipal*831ities would not serve the goals of punishment or deterrence in the same way as punitive damage awards against individuals found to have violated Section 1983. This reasoning is fully applicable to SEPTA. Awarding punitive damages against SEPTA might result in increased taxes or fares and thus punish taxpayers and users of mass transportation who cannot be regarded, except perhaps in an indirect and abstract sense, as bearing any guilt for constitutional violations that SEPTA may commit. See Feingold, 517 A.2d at 1277 (punitive damages against SEPTA would be assessed “effectively against taxpayers and the public at large.”). See also Toombs v. Manning, 835 F.2d 453 at 463. Similarly, the deterrent effect that such awards may have on SEPTA decision makers is far more speculative than the deterrent effect of punitive damage awards on individuals who violate Section 1983, and other means of deterring violations by SEPTA officials — including the assessment of damages against offending the officials themselves and adverse employment actions against such officials — are already available. Finally, SEPTA would be a tempting target for large punitive damage awards by juries unduly influenced by SEPTA’s size and revenues, which greatly exceed those of many municipalities.
In sum, we believe that the Supreme Court’s reasoning in City of Newport is applicable to SEPTA, and we consequently conclude that SEPTA, like a municipality, is immune from punitive damages under Section 1983.
VII.
In conclusion, we hold that SEPTA is not protected by the Eleventh Amendment, that the drug test administered to Bolden was unconstitutional, that SEPTA is not liable for wages lost by Bolden after the settlement between SEPTA and his union, and that punitive damages cannot be assessed against SEPTA under Section 1983. We will therefore affirm the judgment of the district court insofar as it holds that SEPTA is liable for violating Bolden’s constitutional rights, but we will vacate the awards of damages and remand for further proceedings related to this issue.
. The background and details of this policy are discussed in our opinion in Transport Workers’ Local 234 v. SEPTA, 863 F.2d 1110, 1113-15 (3d Cir.1988), vacated, 492 U.S. 902, 109 S.Ct. 3208, 3209, 106 L.Ed.2d 560 (1989), reaffirmed, 884 F.2d 709 (3d Cir.1989).
. SEPTA Order 87-2 provided in relevant part:
Any employee returning to work under the following circumstances may be subject to a medical examination, including body fluid testing: 1. Absences due to physical problems such as injury occurring on or off- duty, and illness; 2. A rehabilitation program for substance abuse which lasted for any length of time; 3. a disciplinary suspension; 4. Any other approved absence from duty in excess of 30 days, (excluding a five-week vacation period).
Refusal to submit to the aforementioned medical examination will subject employees to the disciplinary measures outlined under policy 85-1.
App. at 980.
. Although the district court’s later reported opinion stated that Order 87-2 had also been preliminarily enjoined (see Transport Workers, Local 234, 678 F.Supp. 543, 547 (E.D.Pa.1988)), the same district court judge made clear in this case that the preliminary injunction applied only to Order 87-1. See 10/20/89 Order-Memorandum at 3 & n. 3.
. The Supreme Court vacated our decision and remanded for reconsideration in light of its subsequent decisions in Skinner v. Railway Labor Executives Ass'n, 489 U.S. 602, 109 S.Ct. 1402, 103 L.Ed.2d 639 (1989), and Consolidated Rail Corp. v. Railway Labor Executives Ass’n, 491 U.S. 299, 109 S.Ct. 2477, 105 L.Ed.2d 250 (1989). On remand, we reaffirmed the portion of our decision that had upheld SEPTA’s testing program for safety-sensitive positions, but we had no occasion to address the return-to-work question because SEPTA chose to abandon that issue. 884 F.2d at 711 n. 1.
. Order 85-1 is discussed in Transport Workers, Local 234 v. SEPTA, 678 F.Supp. 543, 545 & n. 4f (E.D.Pa.1988).
. See, e.g., Monell v. Department of Social Services of the City of N.Y., 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978) (actions of local governments may violate individuals’ constitutional rights against the states and give rise to causes of action under Section 1983).
. In Urbano, we ultimately found that abstention was appropriate, and therefore we did not decide whether the agency involved in that case, the Board of Managers of the New Jersey State Prison, was protected by the Eleventh Amendment. See 415 F.2d at 1253-58.
. Although our decision in Skehan v. Board of Trustees of Bloomsburg State College, 538 F.2d 53, 62 (3d Cir.1976), cert. denied, 429 U.S. 979, 97 S.Ct. 490, 50 L.Ed.2d 588 (1976), might suggest that state law characterization is the only relevant consideration in determining if an agency is entitled to raise the Eleventh Amendment defense, such a reading would be in error. State law extending sovereign immunity to an agency is relevant to the Eleventh Amendment determination (see Skehan, 538 F.2d at 62, citing state law determination of sovereign immunity in Brungard v. Hartman, 12 Pa.Cmwlth. 477, 315 A.2d 913 (Pa.Commw.Ct.1974)), but it is not dispositive. In Brungard, the plaintiff alleged state ownership and operation of the agency. 315 A.2d at 914. In Skehan, the agency was not separately incorporated. Skehan v. Board of Trustees of Bloomsburg State College, 501 F.2d 31 (3d Cir.1974), vacated on other grounds, 421 U.S. 983, 95 S.Ct. 1986, 44 L.Ed.2d 474 (1975), on remand, 538 F.2d 53 (3d Cir.1976). Thus, a state law determination of sovereign immunity may coincide with and influence the federal law determination of Eleventh Amendment status, but the former does not conclusively determine the latter.
. The Supreme Court subsequently held that, if the Port Authority was otherwise eligible to raise the defense, New York and New Jersey had waived the Eleventh Amendment defense in the compact by expressly consenting to suit against the Authority in federal court.

Without objection from the parties, the district court in this case instructed the jury to balance Bolden’s privacy interests against SEPTA's asserted need for testing and to determine whether the test was reasonable under the circumstances. 3/15/1990 Tr. at 8-12. This ap*823proach was incorrect. The task of balancing the competing interests in this context must be performed by the courts, not by juries.

Bertine, 479 U.S. 367, 107 S.Ct. 738, 93 L.Ed.2d 739 (1987) (court determines reasonableness of search); United States v. Salmon, 944 F.2d 1106 (1991) (same). The reasonableness of a search or seizure must be determined based on constitutional law, not a factual, reasonable-person determination. If the Fourth Amendment balancing process were submitted to juries, conflicting decisions regarding the constitutionality of identical drug testing provisions would almost certainly result.
While the submission of this question to the jury was erroneous, reversal on this ground is not required. SEPTA did not object to the court’s instruction. Moreover, it is clear that the jury’s finding — that compulsory drug testing of Bolden was unconstitutional — was correct.
. Judge Mansmann would hold that SEPTA has not preserved the issue of Bolden's consent as a defense to its liability and cannot raise the issue on appeal. Thus she would not reach the merits of the consent dispute.

. In Gilmer v. Interstate/Johnson Lane Corp., - U.S. -, 111 S.Ct. 1647, 1656-57, 114 L.Ed.2d 26 (1991), the Supreme Court explained that McDonald and the prior cases "did not involve the issue of the enforceability of an agreement to arbitrate statutory claims” but rather "the quite different issue whether arbitration of contract-based claims precluded subsequent judicial resolution of statutory claims.” Since the collective bargaining agreement in this case did not require arbitration of Section 1983 claims, this case falls within the Alexander-Barrentine-McDonald line of cases.
. Whereas a search or seizure comports with the Fourth Amendment if conducted pursuant to voluntary consent, rights under Title VII and the Fair Labor Standards Act may not be prospectively waived, as the Court pointedly noted in Alexander, 415 U.S. at 51-52, 94 S.Ct. at 1021-22, and Barrentine, 450 U.S. at 740, 101 S.Ct. at 1444.
. Although the collective bargaining agreement in effect at the time of Bolden's test did not contain express drug testing provisions, the 1989-92 collective bargaining agreement contains such provisions. Exhibit to Defendant SEPTA’s Motion for Summary Judgment Against the Plaintiffs.
. Even if Bolden’s union had lacked actual authority to consent to future drug testing on his behalf, SEPTA would not have violated the Fourth Amendment by conditioning Bolden’s continued employment on submission to future drug testing. A search is constitutional if it is based on reasonable belief that a third party had authority to consent. Ill. v. Rodriguez, — U.S. -, 110 S.Ct. 2793, 111 L.Ed.2d 148 (1990). Here, SEPTA had reasonable grounds to believe that the union possessed the authority to consent to future drug testing of Bolden. As noted, the union was Bolden's exclusive collective bargaining representative, and the union had represented Bolden regarding the first grievance a short time earlier and had secured his reinstatement. During the same period, the union also represented dozens of other SEPTA employees in grievances based on drug testing. Under these circumstances, SEPTA’s reliance on the union’s authority to settle Bolden’s grievance and to consent to future drug testing was reasonable. Therefore, SEPTA’s insistence *829upon compliance with the settlement as a condition of employment did not violate Bolden’s Fourth Amendment rights.
. This is a question of law over which we exercise plenary review.
. The Pennsylvania Supreme Court’s decision in Feingotd v. SEPTA, 517 A.2d 1270 (1986), although not dispositive on the question of federal law now before us, is instructive because of its recognition of SEPTA’s governmental character. Noting that "government agencies” have long been exempt from the imposition of punitive damages under Pennsylvania law {id. at 1276), the court held that SEPTA's governmental character entitled it to the same immunity. See also Toombs v. Manning, 835 F.2d 453, 460-65 (3d Cir.1987) (in banc) (holding that SEPTA is a “Commonwealth party’ under Pennsylvania’s sovereign immunity statute).
