delivered the opinion of the Court.
Petitioners are the six maritime unions which appeared before this Court as respondents in Windward Shipping v. American Radio Assn., 415 U. S. 104 (1974). We granted their petition for certiorari to the Supreme Court of Alabama, 415 U. S. 947, in order to review their contentions that this case was distinguishable from Windward on the pre-emption issue, and that the temporary injunction upheld by that court had infringed rights guaranteed to them under the First and Fourteenth Amendments to the United States Constitution.1
As in Windward, this ease arises from picketing designed to publicize the adverse impact on American seamen of the operations of foreign-flag carriers which employ foreign crewmen at wages substantially below those paid to American seamen. As in Windward, the picketing occurred during 1971, but in this case it took place in Mobile, Ala., and was directed against the Aqua Glory, a ship of Liberian registry. The pickets displayed the same signs and distributed the same literature as they did in Windward,2 and they were subject to the same instructions.
*218The picketing in each case also had similar results. In Windward, we observed: “The picketing, although neither obstructive nor violent, was not without effect. Longshoremen and other port workers refused to cross the picket lines to load and unload petitioners’ vessels.” 415 U. S., at 108. Here, the Supreme Court of Alabama, in affirming a temporary injunction issued by the Alabama Circuit Court, said of petitioners’ activities in Mobile:
“Posting the pickets, as was done on the dock adjacent to the Aqua Glory, brought about an immediate refusal by the stevedore workers of the *219locals of International Longshoremen’s Association to cross the picket line of the appellant unions. About eighty percent of the cargo ships that enter the Port of Mobile, sail under a foreign-flag and are manned by alien crews.”3
I
It is apparent from the facts already stated that the Houston picketing in Windward and the Mobile picketing here were for all practical purposes identical. Petitioners refer to Windward as “involving the union petitioners in the identical national picketing dispute as part of the Committee’s program . . . .” Brief for Petitioners 7 n. 1. But petitioners contend that since the state-court plaintiffs in this cáse are not the foreign owners of a picketed ship, as they were in Windward, but are instead stevedoring companies which seek to service the ship 4 and a shipper who wishes to have his crops loaded on it, the question of pre-emption of state-court jurisdiction by the National Labor Relations Act should be answered differently than it was in Windward.5 Petitioners reason that respondents could have charged them with an unfair labor practice under the secondary boycott provision of the National Labor Relations Act, §8 (b)(4), 49 Stat.' 452, as amended, 29 U. S. C. §158 (b)(4), and that since petitioners’ activities were arguably prohibited under that section, the respondents’ exclusive remedy was to seek relief from *220the National Labor Relations Board. Cf. San Diego Building Trades Councils. Garmon, 359 U. S. 236 (1959).
Petitioners’ position in this respect contrasts markedly with their posture in the Windward litigation. There petitioners, as respondents in this Court, urged that “peaceful and truthful primary picketing, non obstructive and without trespass upon private property, by American workers protesting substandard wages and benefits paid,” are activities “actually protected by the Act.” Brief for Respondents in No. 72-1061, O. T. 1973, p. 15. They also urged that “the American seamen’s activities at bar constitutes [sic] typical lawful primary picketing, sanctioned and protected by the Act, Garner [v. Teamsters Union, 346 U. S. 485 (1953),] and [Longshoremen v.] Ariadne [Co.], 397 U. S. [195,] 202 [(1970)].” Brief for Respondents in No. 72-1061, O. T. 1973, p. 16. Petitioners apparently urged the same arguments in the Texas Court of Civil Appeals, whose judgment we reviewed in Windward, because that court stated:
“[Ajppellees’ picketing carefully remained within the guidelines for permissible picketing on the premises of a secondary employer promulgated in Sailor’s Union of the Pacific, 92 N. L. R. B. 547 and adopted in Local 761, Inter. Union of Elec., Radio and Mach. Wkrs. v. NLRB, 366 U. S. 667 .. . (1961).”6
Petitioners, having failed to persuade this Court in Windward that their Houston picketing was protected under § 7 of the National Labor Relations Act, 29 U. S. C. § 157, now contend that their Mobile picketing was at least arguably a secondary boycott prohibited by § 8 (b) (4)(B) of the Act, 29 U. S. C. § 158 (b)(4)(B). They would have us hold not only that there is an independent controversy between petitioner unions, representing *221American seamen, and the contracting stevedores represented by respondent, but also that this independent dispute is subject to the jurisdiction of the Board.
Acceptance of petitioners’ argument would result in a rule whereby a state court had jurisdiction over a complaint for injunction filed by a foreign-ship owner claiming that picketing activities of a union were interfering with his business relationships with a contract stevedore, but the same court would have no jurisdiction where the contract stevedore sought an injunction on precisely the same grounds. The anomaly of such a result is reason enough to question it, but we believe that there is a more fundamental flaw in petitioners’ claim.
Even if there is a dispute between petitioners and respondents which is, in some semantic sense, independent of petitioners’ dispute with foreign-flag ships, that dispute is subject to state-court disposition unless it satisfies the jurisdictional requirements of the NLRA. In this regard, we note that a necessary predicate for a finding by the Board of an unfair labor practice under § 8 (b) (4) (i) is that the individual induced or encouraged must be employed by a “person engaged in commerce or in an industry affecting commerce.” Similarly, a necessary predicate for finding an unfair labor practice under § 8 (b) (4) (ii) is that the person threatened, coerced, or restrained must have been engaged in “commerce or in an industry affecting commerce,” and a necessary predicate for Board jurisdiction of unfair labor practices under § 10 (a) of the Act, 29 U. S. C. § 160 (a) is that they be practices “affecting commerce.”
Petitioners interpret Windward as having done nothing more than establish that the maritime operations of foreign ships are not “in commerce.” They assume that Windward said nothing about either the business activities of persons seeking to deal with such ships, or about whether, for these purposes, those activities are “in commerce” or “affecting commerce.” Petitioners therefore *222are able to state that the requirements of §§ 8 (b) (4) and 10 are satisfied because:
“Unquestionably, the Association, constituting stevedoring companies employing longshoremen to load and discharge vessels at the port of Mobile, Alabama, is an 'employer’ engaged in ‘commerce’ under the Act, and equally unquestionably, respondent Malone, delivering his soybeans to the dock elevator, is a ‘person’ engaged in ‘commerce,’ under the Act.” Brief for Petitioners 15-16.
We do not believe, however, that the line of cases7 commencing with Benz and culminating in Windward permit such a bifurcated view of the effects of a single group of pickets at a single site.
In Windward we stated that our task was to determine “whether the activities . . . complained of were activities ‘affecting commerce’ within the meaning of . . . the National Labor Relations Act,” 8 and we concluded that they were not. 415 U. S., at 105-106. We recognized that the picketing activities did not involve the inescapable intrusion into the affairs of . foreign ships that was present in Benz and Inores, but we went on to say that *223the latter cases “do not purport to fully delineate the threshold of interference with the maritime operations of foreign vessels which makes the LMRA inapplicable.” 415 U. S., at 114. We further observed:
“At the very least, the pickets must have hoped to exert sufficient pressure so that foreign vessels would be forced to raise their operating costs to levels comparable to those of American shippers, either because of lost cargo resulting from the longshoremen’s refusal to load or unload the vessels, or because of wage increases awarded as a virtual self-imposed tariff to regain entry to American ports. Such a large-scale increase in operating costs would have more than a negligible impact on the ‘maritime operations’ of these foreign ships, and the effect would be by no means limited to costs incurred while in American ports. Unlike Ariadne, the protest here could not be accommodated by a wage decision on the part of the shipowners which would affect only wages paid within this country.” 9 Ibid. (Emphasis supplied.)
*224While we thus spoke in Windward of the effect of the Houston pickets on the maritime operations of foreign ships, the quoted passage shows that we fully recognized that this effect would not be produced solely by the pickets and the messages carried by their signs. It would be produced in large part by the refusal of American workmen employed by domestic stevedoring companies to cross the picket line in order to load and unload cargo coming to or from the foreign ships. Since Windward held that the Houston picketing was not in or affecting commerce, it would be wholly inconsistent to now hold, insofar as concerns Board jurisdiction over a complaint by respondents, that the employer of the longshoremen who honored the picket line, or the shipper whose goods they did not handle, was in or affecting commerce.
That we found it unnecessary to expressly state this conclusion in Windward suggests not that the point is an undecided one, but that such a conclusion inevitably flows from the fact that the response of the employees of the American stevedores was a crucial part of the mechánism by which the maritime operations of the foreign ships were to be affected. The exaction of the “self-*225imposed tariff to regain entry to American ports” does not depend upon American shippers heeding the message on the picket signs and declining to ship their cargoes in foreign bottoms. The same pressure upon the foreign-flag owners will result if longshoremen refuse to load or unload their ships. The effect of the picketing on the operations of the stevedores and shippers, and thence on these maritime operations, is precisely the same whether it be complained of by the foreign-ship owners or by persons seeking to service and deal with the ships. The fact that the jurisdiction of the state courts in this case is invoked by stevedores and shippers does not convert into “commerce” activities which plainly were not such in Windward.10
Our dissenting Brethren contend that our disposition is inconsistent with the Court’s decision in Hattiesburg Building & Trades Council v. Broome, 377 U. S. 126 (1964), and with the Board’s decision in Sailors’ Union of the Pacific (Moore Dry Dock), 92 N. L. R. B. 547 (1950). Hattiesburg dealt with the quite different question of applying the Board’s own limitation of its statutory jurisdiction to those cases which have “a substantial effect on commerce.” 23 N. L. R. B. Ann. Rep. 7 (1958) (emphasis added). The Board had promulgated a series of administratively established standards, in effect ceding to state courts and agencies disputes involving entities which admittedly “affected commerce,” but whose volume of interstate business was not “sufficiently substantial to warrant the exercise of [Board] jurisdiction.” 29 *226U. S. C. § 164 (c). The standards provided that they could be “satisfied by reference to the business operations of either the primary or the secondary employer.” Hattiesburg, supra, at 126. Because of this provision, the Board had not in fact ceded its jurisdiction over the particular dispute that had been presented to the Mississippi courts. In Hattiesburg this Court did no more than enforce the natural consequence of this fact by holding that Garmon deprived the state courts of jurisdiction. We find nothing in that holding inconsistent with what we say or hold here. Certainly Hattiesburg does not, as Mr. Justice Stewart’s dissent would have it, stand for the proposition that a secondary employer’s domestic business activities may be the basis for Board jurisdiction where the primary dispute is beyond its statutory authority over unfair labor practices “affecting commerce.” 29 U. S. C. § 160 i,a).
That dissent’s treatment of Moore Dry Dock, supra, reads a great deal more into that 1950 Board decision than its language and analysis can support. The decision itself contains no reference whatever to the jurisdiction of the Board over the primary employer, the foreign-flag vessel Phopho, and neither the decision nor the Trial Examiner’s report considered the jurisdictional challenge presently confronting this Court. The Trial Examiner’s report, from which that dissenting opinion quotes, did state that the Board, in an apparently unreported determination, had previously dismissed a petition for election aboard the Phopho, 92 N. L. R. B. 547, 560-561. The report later acknowledged that the Board had “left somewhat obscure the precise legal basis” of its jurisdictional ruling, a comment which was evoked by the contention that because the primary employer was “clearly engaged in commerce,” the ruling must have been based on a different jurisdictional defect. Id., at 568. This Court in Benz v. Compania Naviera Hidalgo, 353 U. S. 138 (1957), not only noted that Moore *227Dry Dock involved a different situation, but also rather pointedly stated: “We need only say that these cases are inapposite, without, of course, intimating any view as to their result.” 353 U. S., at 143 n. 5. A 1950 Board precedent such as this can scarcely be regarded as controlling when it is clearly contrary to the thrust of this Court’s Benz-Windward line of cases.
Petitioners rely on Teamsters Union v. N. Y., N. H. & H. R. Co., 350 U. S. 155 (1956), and Plumbers’ Union v. Door County, 359 U. S. 354 (1959), for the proposition that even though the Board may not have jurisdiction over the primary labor relations of a party which is excluded from the Act’s definition of “employer,” 11 it is nonetheless competent to consider secondary disputes involving such a party. In Teamsters Union, supra, a railroad was held to be barred from seeking relief in the state courts against a secondary boycott. The Court held that while the railroad was not a statutory “employer,” it was nonetheless a “person” protected by § 8 (b)(4). A similar result was reached in Door County, supra, in which a non-“employer” county sought state court relief, not with respect to activities of its own employees, but with respect to a claimed secondary boycott arising from picketing against a nonunion subcontractor working on an addition to the county courthouse. While these cases establish the proposition that an entity which is not within the Act’s definition of “employer” *228may nonetheless be a “person” for purposes of protection against secondary boycotts, neither they nor any other case decided by this Court suggests that the Board has jurisdiction of § 8 (b) (4) complaints if the alleged unfair labor practice does not affect commerce. Indeed, in Door' County, supra, the Court pointedly inquired whether the out-of-state origin of construction materials was sufficient to establish the jurisdictionally required effect on interstate commerce. 359 U. S., at 356.
Here, neither the farmer seeking to ship his soybeans, the stevedores who contracted to unload the cargo of the foreign-flag vessel, nor the longshoremen whom the stevedores employed to carry out this undertaking, were for these purposes engaged in or affecting commerce within the purview of the National Labor Relations Act. Therefore the petitioners’ picketing did not even “arguably” violate § 8 (b) (4) (B) of that Act. Since Congress did not intend to strain through the filament of the NLRA picketing activities which so directly affect the maritime operations of foreign vessels, we hold that the Alabama courts were competent to apply their own law in resolving the dispute between petitioners and respondents unless, as petitioners claim, such a resolution violated petitioners’ rights under the First and Fourteenth Amendments.
II
After concluding that the state courts had jurisdiction, the Supreme Court of Alabama considered whether the picketing was protected by the First and Fourteenth Amendments. Relying on Teamsters Union v. Vogt, Inc., 354 U. S. 284 (1957), it concluded that if the picketing compromised valid public policies, it was not protected by its putative purpose of conveying information. The court therefore thought that the matter narrowed to whether or not the picketing had a purpose or objective to “wrongfully interfere” with respondents’ businesses. Recognizing that the unions were appealing a temporary in*229junction, issued as a matter of equitable discretion to preserve the status quo pending final resolution of the dispute, the court inquired only whether there was evidence of a prohibited purpose sufficient to establish that the trial judge had not abused the “wide discretion” he possesses in such matters. The court found such evidence in the testimony of a local union official charged with carrying out the picketing. He had expressed the hope that union men would not cross the lines, that the port would become cluttered with foreign ships unable to load or unload, and that the docks would be shut down. On this basis the court concluded that a substantial question was presented as to whether the picketing had a prohibited purpose, and that the trial judge had not abused his discretion.
Petitioners repeat their First and Fourteenth Amendment arguments before this Court. They contend that the picketing was expressive conduct informing the public of the injuries they suffer at the hands of foreign ships, and “imploring the public” to “ ‘Buy American’ or ‘Ship American.’ ” Brief for Petitioners 21. This conduct, they contend, constitutes “the lawful exercise of protected fundamental rights of free speech,” and is thus not subject to injunction.
We think this line of argument is foreclosed by our holding in Vogt, supra. There the Court, in an opinion by Mr. Justice Frankfurter, reviewed the cases in which we had dealt with disputes involving the interests of pickets in disseminating their message and of the State in protecting various competing economic and social interests. Vogt endorsed the view that picketing involves more than an expression of ideas, 354 U. S., at 289, and referred to our “growing awareness that these cases involved not so much questions of free speech as review of the balance struck by a State between picketing that involved more than ‘publicity’ and competing interests of state policy.” Id., at 290. The Court con-*230eluded that our cases “established a broad field in which a State, in enforcing some public policy, whether of its criminal or its civil law, and whether announced by its legislature or its courts, could constitutionally enjoin peaceful picketing aimed at preventing effectuation of that policy.” Id., at 293. We believe that in the case now before us Alabama’s interference with petitioners’ picketing is well within that “broad field.”
Petitioners seek to escape from Vogt in three ways. First, they contend that this case is squarely controlled by Food Employees v. Logan Valley Plaza, 391 U. S. 308 (1968). In that case, claim petitioners, picketing “identical as at bar, [designed] to peacefully and truthfully publicize substandard wages and concomitantly request the public not to patronize the picketed entity,” was held to be protected. Brief for Petitioners 20. In rejecting this contention, we need only point out that Logan Valley concerned the location of picketing, not its purpose; indeed, it was on exactly this basis that the Logan Valley Court distinguished the line of cases culminating in Vogt. 391 U. S., at 314. Logan Valley established only that in some circumstances private business property can be so thoroughly clothed in the attributes of public property that it may not be completely closed as a public forum to those who wish to present otherwise lawful communications.
Petitioners’ second argument is that the injunction here is not supported by a “valid public policy,” as required by Vogt. They point out that while the Alabama Supreme Court stated the public policy to be the prevention of “wrongful interference” with respondents’ businesses, it did not expressly define that term. We, however, think it obvious that in this context “wrongful interference” refers to efforts by third parties to induce employees to cease performing services essential to the conduct of their employer’s business. That third-party participation is critical to picketing being categorized as *231“wrongful interference” is clear from Pennington v. Birmingham Baseball Club, 277 Ala. 336, 170 So. 2d 410 (1964), a case cited by the Alabama Supreme Court in its opinion in this case.
In Pennington the Supreme Court of Alabama indicated that the state policy against “wrongful interference” is quite analogous to the federal policy of prohibiting secondary boycotts, and is based on similar considerations. The State’s policy also appears to be based on the state interest in preserving its economy against the stagnation that could be produced by pickets’ disruption of the businesses of employers with whom they have no primary dispute. At Mobile the picketing threatened to eliminate the 70% to 80% of the stevedores’ business that depended on foreign shipping, and to cause serious losses for farmers whose agricultural crops required immediate harvesting and shipping.12 Under Vogt, supra, the State may prefer these interests over petitioners’ interests in conveying their “ship American” message through the speech-plus device of dockside picketing.
Petitioners’ final contention is that the record fails to support the conclusion that a substantial question existed as to whether the picketing constituted “wrongful interference” under Alabama law. The question of whether evidence is sufficient to make out a cause of action created by state law and tried in the state courts is a matter for decision by those courts. Insofar as petitioners’ argument on this score may be read to suggest that the evidence before the Alabama court would not support-a finding that their activities were such as could be enjoined under Vogt, supra, we reject it. Petitioners seem to argue that the Alabama courts were bound by *232the statements of purpose appearing on the pickets’ signs and literature, and that in any event one local official’s statements of his hopes and expectations as to the picketing’s effect could not override those stated purposes. This argument ignores the wide latitude open to triers of fact to make factual determinations on the basis of rational inferences which arise from the nature, location, and effect of picketing. See Vogt, supra, at 286, 295; Plumbers Union v. Graham, 345 U. S. 192, 197-200 (1953).
Concluding that the jurisdiction of the Alabama courts in this case was not pre-empted by the National Labor Relations Act, and that the action of those courts in enjoining the picketing at Mobile violated no right conferred upon petitioners by the First and Fourteenth Amendments, we affirm the judgment of the Supreme Court of Alabama.
Affirmed.
The decision of the Supreme Court of Alabama is reported at 291 Ala. 201, 279 So. 2d 467 (1973). Because that court validated only a temporary injunction, and remanded for trial on the merits, an issue has been raised as to our jurisdiction to consider this case. We think that Construction Laborers v. Curry, 371 U. S. 542 (1963), is conclusive of the finality of the judgment below for the purposes of 28 U. S. C. § 1257.
The pickets carried signs which read:
“ATTENTION TO THE PUBLIC THE WAGES AND BENEFITS PAID ABOARD THE VESSEL SS [name of vessel] ARE SUB*218STANDARD TO THOSE OF THE AMERICAN SEAMEN. THIS RESULTS IN EXTREME DAMAGE TO OUR WAGE STANDARD AND THE LOSS OF OUR JOBS. PLEASE DO NOT PATRONIZE [THIS VESSEL] j HELP THE AMERICAN SEAMEN. WE HAVE NO DISPUTE WITH OTHER VESSELS AT THIS SITE.”
[Printed names of the six unions.] App. 6a.
They distributed literature which stated:
“To the Public — American Seamen have lost approximately 50% of their jobs in the past few years to foreign flag ships employing seamen at a fraction of the wages of American Seamen.
“American dollars flowing to these foreign shipowners operating ships at wages and benefits substandard to American Seamen, are hurting our balance of payments in addition to hurting our economy by the loss of jobs.
“A strong American Merchant Marine is essential to our national defense. The fewer American flag ships there are, the weaker our position will be in a period of national emergency.
“PLEASE PATRONIZE AMERICAN FLAG VESSELS, SAVE OUR JOBS, HELP OUR ECONOMY AND SUPPORT OUR NATIONAL DEFENSE BY HELPING TO CREATE A STRONG AMERICAN MERCHANT MARINE.
“Our dispute here is limited to the vessel picketed at this site, the S. S.-” Id., at 7a.
[Printed names of the six unions.]
291 Ala., at 205, 279 So. 2d, at 470.
The stevedoring companies appear here through their bargaining representative, Mobile Steamship Association, Inc.
Petitioners also suggest that the result should be different because Windward did not involve vessels which, while flying foreign flags, were American owned. Petitioners do not, however, direct our attention to any evidence in the record as to the ownership of the Aqua Glory. In any event, we think this factor irrelevant, in light of McCulloch v. Sociedad Nacional, 372 U. S. 10, 19 (1963).
Windward Shipping v. American Radio Assn., 482 S. W. 2d 675, 678 (1972).
Benz v. Compania Naviera Hidalgo, 353 U. S. 138 (1957); McCulloch v. Sociedad Nacional, 372 U. S. 10 (1963); Incres S. S. Co. v. Maritime Workers, 372 U. S. 24 (1963).
The relevant definitions appear in 29 U. S. C. §§ 152 (6) and (7):
“(6) The term 'commerce’ means trade, traffic, commerce, transportation, or communication among the several States, or between the District of Columbia or any Territory of the United States and any State or other Territory, or between any foreign country and any State, Territory, or the District of Columbia, or within the District of Columbia or any Territory, or between points in the same State but through any other State or any Territory or the District of Columbia or any foreign country.
“(7) The term ‘affecting commerce’ means in commerce, or burdening or obstructing commerce or the free flow of commerce, or having led or tending to lead to a labor dispute burdening or obstructing commerce or the free flow of commerce.”
Our Brother Stewart suggests in dissent that Longshoremen v. Ariadne Co., 397 U. S. 195 (1970), requires reversal here, because in that case it was held that longshoremen servicing foreign-flag vessels in American ports are in “commerce” within the meaning of the Act. But the Ariadne court, in distinguishing Benz, supra, and McCulloch, supra, stated that “[t]he considerations that informed the Court’s construction of the statute” in those cases “are clearly inapplicable to the situation presented here. The participation of some crew members in the longshore work does not obscure the fact that this dispute centered on the wages to be paid American residents, who were employed by each foreign ship not to serve as members of its crew but rather to do casual longshore work.” 397 U. S., at 199. The Court in Windward reiterated that distinction:
“The pickets in Ariadne, unlike the pickets in Benz or lucres, were primarily engaged in a dispute as to whether an employer should hire unionized or nonunionized American workers to perform long*224shoremen’s work, and the substandard wages which they were protesting were being paid to fellow American workers.” 415 U. S., at 112.
Here the picketing which triggered the dispute was not directed toward any wages or conditions of employment of the longshoremen. It was instead directed to substandard wages being paid to the crews of foreign-flag vessels throughout those vessels’ worldwide maritime operations. In Ariadne, on the contrary, the picketing was directed toward requiring a foreign-flag vessel to hire unionized American workers, rather than nonunionized American workers, to service vessels berthed in American ports. That the latter effect does not surpass “the threshold of interference with the maritime operations of foreign vessels which makes the LMRA inapplicable,” Windward, supra, at 114, certainly provides no support for the proposition that the former effect also does not surpass that threshold.
In so holding, we need cast no doubt on those cases which hold that the Board has jurisdiction under § 8 (b) (4) of domestic secondary activities which are in commerce, even though the primary employer is located outside the United States. See Madden v. Grain Elevator Workers Local 418, 334 F. 2d 1014 (CA7 1964), cert. denied, 379 U. S. 967 (1965); Grain Elevator Workers Local 418 v. NLRB, 126 U. S. App. D. C. 219, 376 F. 2d 774, cert. denied, 389 U.S. 932 (1967).
The definition appears in 29 U. S. C. § 152 (2):
“(2) The term ‘employer’ includes any person acting as an agent of an employer, directly or indirectly, but shall not include the United States or any wholly owned Government corporation, or any Federal Reserve Bank, or any State or political subdivision thereof, or any corporation or association operating a hospital, if no part of the net earnings inures to the benefit of any private shareholder or individual, or any person subject to the Railway Labor Act, as amended from time to time, or any labor organization (other than when acting as an employer), or anyone acting in the capacity of officer or agent of such labor organization.”
The record indicates that all grain storage facilities in the Mobile area were full. Additional soybeans could be harvested only as those already stored were transferred to waiting vessels. App. 77a-80a.
