Ruth Hayworth ("Hayworth") filed a wrongful death action against Fruehauf Corporation ("Fruehauf")1 after her husband was killed in a work-related accident involving a dump truck manufactured by Fruehauf. Pursuant to Ind.Appellate Rule 4(B)(6), she brings this interlocutory appeal from the trial court's order enjoining the testimony of her expert witness. Hayworth raises three issues for our review, which we consolidate into two and restate as follows:
I. Whether Fruchaufs motion for in-junctive relief is barred by collateral estoppel.
II. Whether the trial court abused its discretion by enjoining the expert witness retained by Hayworth from participating in the litigation.
The facts most favorable to the trial court's order indicate that on May 9, 1988, Daniel Hayworth was killed in an accident involving a dump truck manufactured by Fruchauf. As executrix of his estate, Ruth Hayworth filed this wrongful death action against Fruehauf. During the discovery process, Hayworth hired engineer George Allan Hagelthorn as an expert witness. Hagel-thorn had been previously employed by Fruehauf as the chief engineer in various departments, most recently serving as Frue-hauf's Manager of Reliability.
Upon discovering that Hagelthorn intended to testify on Hayworth's behalf, Fruchauf filed a motion to enjoin Hagelthorn from participating in the litigation. - Fruchauf based its motion on the attorney-client privilege and the work product doctrine.2 The trial court granted Fruchaufs motion and enjoined Hagelthorn's testimony. On Hayworth's motion, the trial court certified its order as interlocutory and this court accepted Hayworth's petition pursuant to App.R. 4(B)(6).
I.
Collateral Estoppel
Relevant to Hayworth's first allegation of error is a decision by a Michigan county cireuit court denying Fruchauf's motion for a preliminary injunction. Fruchauf's motion filed in Michigan sought to enjoin Hagelthorn from participating in any litigation brought against Fruehauf. Hayworth contends that the Michigan court's decision bars Fruchauf from raising the issue of Hagelthorn's testimony in the instant litiga*604tion. Specifically, Hayworth contends that Fruehauf's motion is barred by offensive collateral estoppel, which occurs when a " 'plaintiff seeks to foreclose the defendant from litigating an issue the defendant has previously litigated unsuccessfully in an action with another party'" Tofany v. NBS Imaging Systems, Inc. (1993), Ind., 616 N.E.2d 1034, 1037, (quoting Parklane Hosiery Co. v. Shore (1979), 439 U.S. 322, 326, n. 4, 99 S.Ct. 645, 649, n. 4, 58 L.Ed.2d 552).
When determining whether offensive collateral estoppel may be asserted in an action, the trial court partakes in a two-step process, considering: 1) whether the party in the prior action had a full and fair opportunity to litigate the issue; and 2) whether it is otherwise unfair to apply collateral estoppel given the particular facts of the case. Tofany, supra at 1038. Additionally, in determining whether collateral estoppel may be used offensively, the court must consider whether the plaintiff could have easily joined in the first action, and whether the application of collateral estoppel would be unfair to the defendant. Id. The trial court's decision to disallow the offensive use of collateral estop-pel will be reversed only upon a showing of abuse of discretion. Id. at 1039.
The record before us supports the trial court's conclusion that offensive collateral es-toppel is inapplicable to this case. Although both the Michigan litigation and the case at bar involve the testimony of Hagelthorn in actions against Fruchauf, the issue is clearly not the same. The Michigan action sought to enjoin Hagelthorn from participating in any case in which Fruechauf was a defendant, regardless of the nature of the case or Hagelthorn's prior involvement in the particular issues raised. The case at bar seeks to enjoin Hagelthorn's testimony in a specific instance: in a case involving the safety of a Fruehauf dump truck, an area for which Hagelthorn had significant responsibility while employed at Fruchauf.
This difference is significant, especially in light of the fact that injunctive relief is at issue. The balance of harms and risks of prejudice to the parties are key factors in the trial court's decision whether to grant or deny injunctive relief. See T.H. Landfill v. Miami County Solid Waste District (1994), Ind.App., 628 N.E.2d 1237, 1238. Because the seope of the injunctive relief sought plays a significant role in determining the balance of harms to the parties, the issue in the case at bar is sufficiently distinguishable from the Michigan action to preclude the application of collateral estoppel.

Attorney-Client Privilege
-It is well established that communications between a client and his attorney, for the purpose of obtaining advice regarding the client's rights and Habilities, are privileged and thus protected from judicially compelled disclosure. See IND.CODE § 34-1-14-5 (1993); Canfield v. Sandock (1990), Ind., 563 N.E.2d 526, reh. denied; Brown v. State (1983), Ind.App., 448 N.E.2d 10, 13-14. This privilege extends to communications between an agent acting on behalf of legal counsel and the client, provided that the communication at issue involves the same subject matter about which the attorney was consulted and the agent was retained by the attorney to assist him in rendering legal advice on the client's behalf. Brown, supra; Huffstutler, infra 61 Ohio St.3d at 345-47, 575 N.E.2d at 119.
Hayworth argues that the trial court abused its discretion in enjoining Hagelthorn's testimony based on attorney-client privilege.3 The grant or denial of an injunction is within the sound discretion of the trial court. On appeal, we will reverse only where the evidence, viewed most favorably to the trial court's decision, leads to a *605conclusion directly opposite to the conclusions of the trial court. Simon v. City of Auburn, Ind. Bd. of Zoning Appeals (1988), Ind.App., 519 N.E.2d 205, 209. Only when the trial court's action is clearly against the logic and effect of the facts and cireum-stances before the court will an abuse of discretion be found. Id.
According to Hayworth, Hagelthorn did not serve either as an attorney or as an agent of legal counsel during his employment at Fruchauf, rendering the attorney-client privilege inapplicable, and the trial court's injunction was improper. - Indiana courts have not yet had occasion to address the applicability of attorney-client privilege in this context; this is an issue of first impression in this jurisdiction.
In support of its argument that the attorney-client privilege should apply under these cireumstances, Fruchauf cites American Motors Corporation v. Huffstutler (1991), 61 Ohio St.3d 343, 575 N.E.2d 116. In Huffstutler, the plaintiff in an action against American Motors Corporation ("AMC") hired Huffstutler to testify as an expert witness in an action involving a rollover of an AMC Jeep. Huffstutler was formerly employed as an engineer for AMC Jeep. During the course of his employment, Huffstutler obtained a law degree and gained admission to the Ohio Bar. Thereafter he became the manager of AMC's Product Design Studies Group, and in his position "worked intimately with the legal department and its privately retained counsel in products lability cases involving AMC Jeep, particularly 'rollover' claims." Id. at 344, 575 N.E.2d at 118. Huffstutler's involvement in AMC's products lability cases included recommending expert witnesses and outside counsel, meeting with experts to prepare defense strategy, suggesting lines of testimony and cross examination, and assisting counsel in the preparation of defenses. Id. Based on the extent of his involvement in litigation, the Ohio Supreme Court concluded that principles of attorney-client privilege were fully applicable to Huffstutler. The court affirmed the trial court's - permanent - injunction - precluding Huffstutler's participation in any litigation involving AMC.
We find this rationale persuasive, as it is consistent with the well settled principles of attorney-client privilege accepted by the Indiana courts.4 See Canfield, supra; Brown, supra. Thus we conclude that under appropriate circumstances, attorney-client privilege may bar a former employee from testifying as an expert in litigation against his former employer. When faced with this issue, our courts should examine the particular facts and circumstances of each case to determine whether the challenged expert actually served as an agent of legal counsel during his employ.
We must now consider this test in light of the facts and circumstances of this case. The instant record reveals ample evidence that Hagelthorn participated substantially in cases involving the safety and design of Fruehaut's dump trucks. In fact, in his prospectus offering his expert services, Hagel-thorn stated that while employed at Frue-hauf, he "investigate[d] highway accidents involving Fruchauf trailers and [coordinated Fruehauf's] best means of defense in product liability cases with the Legal Department." Record, p. 483-25; Chosy Deposition Exhibit 5. The record further indicates that Frue-haut's Reliability Department worked closely with the Legal Department and outside counsel on products liability cases, to the extent that Hagelthorn himself drafted correspondence to outside counsel regarding potential legal strategy.5 Record, p. 483-18; Chosy Deposition Exhibit 8.
*606From this evidence the trial court could reasonably conclude that Hagelthorn's involvement in related litigation during his employment at Fruchauf was sufficient to make him an agent of Fruchauf's legal counsel. Thus the trial court did not abuse its discretion in invoking the attorney-client privilege and enjoining Hagelthorn's participation in this action.
Affirmed.
GARRARD, J., concurs. SULLIVAN, J., concurs in result with opinion.. Also named in her lawsuit were Schilli Leasing, Inc., Schilli Transportation Service, Inc., Schilli Motor Lines, Inc. and Geupel DeMars, Inc. Hayworth and Schilli reached a settlement agreement; Geupel DeMars' motion for summary judgment was granted as to all of Hayworth's claims against it. As a result, Fruehauf is the only remaining defendant for purposes of this appeal.
. Because we conclude that Hagelthorn's participation as Hayworth's expert in this litigation is barred by attorney-client privilege, it is unnecessary to reach the issue of the attorney work product doctrine.
. Alternatively, Hayworth argues that Fruchauf has waived attorney-client privilege by utilizing Hagelthorn as an expert witness in unrelated litigation. - Hayworth incorrectly relies on Brown, infra, to support this proposition. In Brown, our supreme court concluded that a defendant could not seek admission of privileged communications during one portion of a criminal proceeding, and then later object to disclosure of the same information when it was sought by the State. Id. at 14-15. Because the instant case involves unrelated proceedings and an unrelated party, the application of waiver adopted in Brown is inapposite.
. Hayworth urges us to reject attorney-client privilege in this context based on the general rule that evidentiary privileges are disfavored and subject to narrow construction by the courts. See Hulett v. State (1990), Ind.App., 552 N.E.2d 47, 49, reh. denied. However, it is equally true that our legislature has recognized a necessity to protect confidential disclosures arising out of certain statutorily protected relationships. See I.C. 34-1-14-5. We believe that examining the applicability of attorney-client privilege in this context on a case by case basis, taking into account the extent of the former employees' involvement in the litigation at issue, gives due credence to both concerns.
. - Hayworth argues that the Huffstutler rationale is distinguishable because unlike Huffstutler, Hagelthorn is not an attorney. However, Huffs-tutler's attorney status was not dispositive; it *606was just one of many factors considered by the Ohio Supreme Court in making its determination. The Ohio court considered the nature and extent of Huffstutler's involvement in the litigation at issue. Id. at 118.
