WARREN, P.J.

In this action for defamation and intentional interference with economic relations, plaintiff appeals from a summary judgment. ORCP 47 C. Defendants cross-appeal from a judgment dismissing their claims for contribution and indemnity against third-party defendant American Telephone and Telegraph (ATT) for failure to state a claim. ORCP 21 A(8).

Plaintiff worked for ATT as a supervisor. In 1989, he began working at an ATT facility in Beaverton. Defendant Dymowski was the union steward of the crew that plaintiff managed at that facility and a vice president of Communications Workers of America Local 7901 (CWA). A few months after plaintiff began working there, Dymowski observed behaviors that led him to believe that plaintiff had an alcohol abuse problem. On several occasions, Dymowski noticed that plaintiff came to work late, was hard to contact during the day and looked like he had a hangover. Other crew members complained about plaintiff's behavior. In February 1990, Dymowski filed a grievance against plaintiff, which concerned plaintiffs order that Dymowski contact him before conducting union business while on the job. That same month, Dymowski had an altercation with plaintiff about an expense voucher. Dymowski called plaintiff's supervisor, Potter, and complained about plaintiff's conduct. Dymowski filed a second grievance. Management resolved both grievances.

Dymowski continued to receive complaints from others about plaintiff. In September 1990, ATT required Dymowski to attend a training seminar. Before Dymowski attended the seminar, an employee who plaintiff had supervised at a different location, Booze, told Dymowski that plaintiff was a "substance abuser." Next, a crew member asked Dymowski to forward the crew's complaints about plaintiff's behavior to Potter. Dymowski agreed to tell Potter "all I know." At the training seminar, Dymowski told Potter that he had been getting complaints from the crew that plaintiff was hard to reach, arrived late to work and took long lunch breaks. He repeated Booze's allegation that plaintiff was a substance abuser. Potter's supervisor, Kastening, was standing nearby and heard the conversation. Later, Potter and Kastening called crew members for more information about plaintiff. In October 1990, ATT removed plaintiff from his job. It offered him another job in California. Plaintiff declined.

Later, plaintiff brought this action, asserting claims for defamation and intentional interference with economic relations against Dymowski and CWA. CWA brought a third-party action for contribution and indemnity against ATT. Plaintiff's defamation claim alleged that Dymowski's statements to Potter at the training seminar were "false and defamatory." The claim for intentional interference with economic relations alleged that defendants intentionally interfered with plaintiff's employment by making false statements about his purported substance abuse or, alternatively, because Dymowski had a personal vendetta against him. Defendants moved for summary judgment against plaintiff. ATT moved to dismiss defendants' third-party complaint for failure to state a claim.

After the summary judgment hearing, the trial court granted plaintiff's motion to amend the complaint to add a second claim for defamation, which alleged, in part:

"Dymowski knew that allegations of substance abuse about Plaintiff were false, or acted in reckless disregard for the truth or falsity of those allegations."

The trial court then granted defendants' motion for summary judgment, concluding that the conduct that formed the basis of plaintiff's first claim for defamation and the claim for intentional interference with economic relations was regulated by the National Labor Relations Act, 29 U.S.C. § 151 et seq (NLRA), and that, therefore, it did not have jurisdiction to hear those claims. Next, it concluded that plaintiff's second claim for defamation presented no genuine issue of material fact. Finally, it granted ATT's motion to dismiss. Plaintiff appeals the summary judgment and defendants cross-appeal the judgment dismissing their third-party complaint for failure to state a claim.

1. We discuss, first, plaintiff's assignments challenging the summary judgment for defendants. To prevail on its summary judgment motion, defendants must show that there is no genuine issue of material fact and that they are entitled to judgment as a matter of law. Seeborg v. General Motors Corporation, 284 Or. 695, 700-01, 588 P.2d 1100 (1978).

2, 3. Plaintiff's first assignment asserts that the trial court erred in granting summary judgment on his first claim for defamation. The issue is whether the conduct that is the basis of liability, Dymowski's allegedly defamatory statement, is within the exclusive jurisdiction of the National Labor Relations Board (NLRB). The NLRA provides for the comprehensive regulation of labor-management relations and vests the NLRB with jurisdiction to resolve disputes involving the regulated conduct. Section 7 of the NLRA, 29 U.S.C. § 157, protects "concerted activities," including the right of employees to "assist labor organizations * * * for the purpose of mutual aid or protection." Section 8 of the NLRA, 29 U.S.C. § 158, prohibits unfair labor practices. In San Diego Unions v. Garmon, 359 U.S. 236, 242, 79 S Ct 773, 3 L Ed 2d 775 (1959), the Supreme Court discussed labor-management relations governed by those sections:

"The nature of the judicial process precludes an ad hoc inquiry into the special problems of labor-management relations involved in a particular set of occurrences in order to ascertain the precise nature and degree of federal-state conflict there involved * * *. * * * To the National Labor Relations Board * * * must be left those precise and closely limited demarcations that can be adequately fashioned only by * * * administration."

In other words, the NLRB has primary jurisdiction over labor disputes involving activities that are, or could even "arguably" be, protected or prohibited by sections 7 or 8. 359 US at 245.

Plaintiff correctly contends that, here, a predicate to NLRA preemption is that Dymowski's statements occurred during a "labor dispute." That term is broadly defined by the NLRA as:

"[A]ny controversy concerning terms, tenure or conditions of employment, or concerning the association or representation of persons in seeking to arrange terms or conditions of employment, regardless of whether the disputants stand in the proximate relation of employer and employee." 29 U.S.C. § 152(a)(9).

The heart of plaintiff's argument is that, in the context of a claim for defamation, the term "labor dispute" applies only to statements made during a union's organizational efforts. In support of that argument, plaintiff cites Lundgren v. Pawtucket Firefighters Ass'n, 595 A.2d 808 (RI 1991). We are not persuaded. In Lundgren, the plaintiffs were firefighter battalion chiefs who brought a claim for defamation against a union. The union argued that the NLRA preempted the claim. The Rhode Island Supreme Court determined that the claim was not preempted, based solely on its conclusion that plaintiffs were not "employees" within the scope of the NLRA. 595 A.2d at 815. See 29 U.S.C. § 152. Therefore, whether or not a labor dispute existed, as that term is defined by the NLRA, was irrelevant to the court's decision.

It is well settled that labor disputes may exist in circumstances that do not involve organizing activities by a union. See, e.g., Jacksonville Bulk Terminals v. Longshoremen, 457 U.S. 702, 711-14, 102 S Ct 2673, 73 L Ed 2d 327 (1982); Railway Labor Exec. Ass'n v. Wheeling Lake Erie Ry., 914 F.2d 53, 55 (4th Cir 1990); Aarco v. Baynes, 391 Mass. 560, 563 n 3, 462 N.E.2d 1107 (1984). That is equally so in claims based on a union's alleged defamatory statements about management. Beverly Hills Foodland, Inc. v. Union, 39 F.3d 191, 194-95 (8th Cir 1994).

Here, the uncontradicted evidence is that Dymowski made the allegedly defamatory statement in the context of telling Potter, plaintiff's supervisor, about complaints he had received from his crew concerning plaintiff's work-related conduct and how it affected work conditions. Under those circumstances, and considering the broad statutory definition, we conclude that the allegedly defamatory statement occurred during a labor dispute as a matter of law. Id. at 195; Hasbrouck v. Sheet Metal Workers 232, 586 F.2d 691, 694 n 3 (9th Cir 1978). Plaintiff's remaining arguments about the issue of whether a labor dispute existed do not require discussion.

The next issue is whether Dymowski's allegedly defamatory statements were actually or arguably protected or prohibited by sections 7 or 8 of the NLRA. In Letter Carriers v. Austin, 418 U.S. 264, 279, 94 S Ct 270, 41 L Ed 2d 745 (1974), the United States Supreme Court discussed whether a state action that was based on an allegedly defamatory statement made during a labor dispute was preempted. There, a union newsletter regularly published, under the heading "List of Scabs," a list of employees who had not joined the union. The plaintiffs successfully brought an action for defamation against the union. On appeal, the union argued that the NLRA preempted the claim. The Supreme Court held that the plaintiffs' claim was preempted unless they could show that the defamatory statement was made with "actual malice," that is, with knowledge of its falsity or with reckless disregard for the truth. 418 US at 275.

Plaintiff's first claim for defamation does not allege that Dymowski made the substance abuse accusations with actual malice. Therefore, if Dymowski's statements to Potter were actually or arguably protected or prohibited by NLRA, sections 7 or 8, plaintiff's first claim for defamation is preempted. 418 US at 271-73. Dymowski's conduct in telling Potter of the crew's complaints about plaintiff's behavior arguably could be protected under NLRA, section 7, because that conduct could have been meant to assist the union "for the purpose of mutual aid or protection." Under those circumstances, we conclude that the trial court correctly determined that the NLRB had primary jurisdiction over plaintiff's first claim for defamation, because it was for the NLRB "to ascertain the precise nature and degree of [the] federal-state conflict." San Diego Unions, 359 US at 242.

4. Plaintiff's next assignment is that the court erred in granting summary judgment on his second claim for defamation. The trial court concluded that there was no genuine issue of material fact about whether Dymowski knew that the substance abuse allegations were false, or that he acted in reckless disregard of the truth. See Letter Carriers, 418 US at 275; Koch v. Laborico, 66 Or. App. 78, 87, 674 P.2d 602 (1983), rev den 296 Or. 712 (1984). Plaintiff argues that the evidence shows that Dymowski believed plaintiff had only a drinking problem and that he was reckless in telling Potter about plaintiff's alleged substance abuse problem. Alternatively, plaintiff argues that the evidence shows that Dymowski had a personal vendetta against him and that the drug abuse allegations were self-serving. Defendants disagree.

In his deposition, Dymowski said that he thought plaintiff had a drinking problem and described plaintiff as having symptoms consistent with a hangover. Dymowski also said that, at one time, he told Potter that he was going to "rip plaintiff's head off." Plaintiff, in his affidavit, denied that he ever had a drug or alcohol problem. In his deposition, plaintiff claimed that Dymowski had a personal vendetta against him and referred to the grievances that Dymowski filed against him, the statement Dymowski made about ripping his head off and Dymowski's general dislike of him.

5. On summary judgment, the existence of questions of credibility generally precludes summary judgment. Koch, 66 Or App at 87. There is evidence from which a trier of fact could conclude that substance abuse is different from alcohol abuse and that Dymowski, for personal reasons, recklessly made allegations about plaintiff's purported substance abuse. We conclude that plaintiff offered sufficient evidence to defeat summary judgment on the issue of whether Dymowski acted with either actual knowledge of the falsity of his statements or with reckless disregard for their truth.

6, 7. Defendants, citing Rice v. Comtek Mfg. of Oregon, Inc., 766 F. Supp. 1550 (D Or 1990), argue that even if a genuine issue of material fact exists on the question of actual malice, Dymowski did not publish the defamatory statement about substance abuse. We disagree. In Rice, the plaintiff moved to amend his complaint to include a claim for defamation. He alleged that the defendant, a corporate officer, told him that he was being fired for "dealing in drugs." The trial court denied the motion, observing that "the majority view holds that 'statements made by one corporate employee during the performance of his duties within the hearing only of other corporate employees does not constitute publication.' Messina v. Kroblin Transp. Sys., Inc., 903 F.2d 1306, 1309 (10th Cir 1990) (Okla law)[.]" 766 F Supp at 1551. Even assuming that Rice correctly identifies the majority rule, we believe that the better rule is set forth in the Restatement (Second) Torts § 577(1) (1976), and comment i:

"(1) Publication of defamatory matter is its communication intentionally or by a negligent act to one other than the person defamed.

"* * * * *

"i. Communication by one agent to another agent of the same principal. The communication within the scope of his employment by one agent to another agent of the same principal is a publication not only by the first agent but also by the principal and this is true whether the principal is an individual, a partnership or a corporation."

We conclude that Dymowski published the allegedly defamatory statement when he communicated it to Potter and Kastening. 8. Next, defendants argue that they had a qualified, or conditional, privilege to defame plaintiff. "A conditional privilege to make a defamatory statement can arise when it is made to protect the interests of an employer or when it is on a subject of mutual concern to the publisher and those to whom it is made." Worley v. OPS, 69 Or. App. 241, 245, 686 P.2d 404, rev den 298 Or. 334 (1984); see also Wattenburg v. United Medial Lab., 269 Or. 377, 380, 525 P.2d 113 (1974). Defendants contend that, because Potter was Dymowski's and plaintiff's superior, he had a "legitimate interest" in learning about plaintiff. Plaintiff argues that Dymowski's motive in making the substance abuse allegation was personal and, therefore, not privileged.

9, 10. Even if Dymowski had an improper motive in making that allegation, if his primary motive was proper, the communication could nonetheless be conditionally privileged. See Schafroth v. Baker, 276 Or. 39, 46-47, 553 P.2d 1046 (1976). Motive is generally not an appropriate factual issue to be disposed of by summary judgment. Welch v. Bancorp Management Services, 57 Or. App. 666, 673, 646 P.2d 57 (1982), aff'd in part, rev in part on other grounds 296 Or. 208, 675 P.2d 172, mod 296 Or. 713, 679 P.2d 866 (1984). That is so here, because there is conflicting evidence about whether or not Dymowski's primary motive when he made the allegedly defamatory statement was personal. We conclude that the trial court erred in granting summary judgment on plaintiff's second claim for defamation.

11. Plaintiff's next assignment is that the trial court erred in granting summary judgment on his claim for intentional interference with economic relations. Plaintiff argues that the court incorrectly concluded that the NLRA preempts that claim. Defendants assert that plaintiff's claim fails because it is preempted and because plaintiff failed to prove that Dymowski used improper means or had an improper motive in making the substance abuse allegations. See Lewis v. Oregon Beauty Supply Co., 302 Or. 616, 621, 733 P.2d 430 (1987).

The issue, again, is whether the conduct that is the basis of liability is actually or arguably protected or prohibited by the NLRA. San Diego Unions, 359 US at 245. If it is, then plaintiff's claim for intentional interference with economic relations is preempted by the NLRA. Id. The conduct on which that claim is based is that Dymowski falsely alleged plaintiff had a substance abuse problem. That conduct, we have already determined, was arguably protected by the NLRA. Because that is the only conduct that is the basis for plaintiff's claim for intentional interference with economic relations, we conclude that the NLRA preempts that claim. See Operating Engineers v. Jones, 460 U.S. 669, 676, 103 S Ct 1453, 75 L Ed 2d 368 (1983). Plaintiff's remaining arguments do not require discussion.

12. Next, we discuss CWA's cross-appeal, in which it assigns error to the dismissal of its claims for contribution and indemnity against ATT for failure to state a claim. In reviewing the granting of a motion to dismiss, we assume the truth of all allegations, as well as any inferences that may be drawn from them, and view them in the light most favorable to the nonmoving party. Oksenholt v. Lederle Laboratories, 294 Or. 213, 215, 656 P.2d 293 (1982). We determine whether the pleading states a claim as a matter of law. Hansen v. Anderson, 113 Or. App. 216, 218, 831 P.2d 717 (1992).

13. The first issue is whether the trial court erred in concluding that CWA's third-party complaint failed to state a claim for contribution. ORS 18.440 governs claims for contribution and provides, in part:

"[W]here two or more persons become jointly or severally liable in tort for the same injury to person or property * * * there is a right of contribution among them even though judgment has not been recovered against all or any of them. There is no right of contribution from a person who is not liable in tort to the claimant."

CWA's third-party complaint for contribution alleges, in part:

"At all times material, defendant Dymowski was acting within the course and scope of his employment of third-party defendant ATT, and any statements made by Dymowski which form the basis of plaintiff's complaint against Dymowski and CWA were made responding to inquiries from Dymowski's superiors at ATT to whom Dymowski had a duty, under penalty of discipline, to respond, and said communications were not promoted by, authorized by, or ratified by defendant CWA.

"Plaintiff's claims for liability against CWA are derivative only, in so far as they allege defendant Dymowski was acting within the course and scope of his agency with CWA when making the communications which form the basis of plaintiff's complaint * * *."

In essence, CWA alleges that, if it is liable for Dymowski's statements, then ATT is also liable, because when Dymowski made those statements, he was also acting in the course and scope of his employment for ATT. Therefore, it is possible that both ATT and CWA could be vicariously liable for Dymowski's allegedly defamatory statements.

ATT argues, citing Rice, that it cannot be liable to plaintiff for defamation. It asserts that, if Dymowski was acting within the course and scope of his employment with ATT, then there was no publication of his allegations of substance abuse, because those allegations were made to ATT, not by ATT. We have already concluded that, under the Restatement (Second) Torts § 577(1), comment i, the communication by one agent to another agent of the same principal within the scope of employment is a publication by the first agent and the principal. Thus, under the facts alleged, ATT could conceivably be held liable, as Dymowski's principal, for publishing a defamatory statement about plaintiff. CWA could also be held liable, because an agent may simultaneously serve two principals. Blair v. United Finance Co., 228 Or. 632, 635, 365 P.2d 1077 (1961). Because CWA has pleaded facts from which it could be inferred that ATT and CWA could be jointly liable for plaintiff's injuries, we conclude that CWA has stated a claim for contribution.

14. The next issue is whether CWA's third-party complaint states a claim for indemnity. As a common law indemnity claimant, CWA must plead, in part, that as between it and ATT, the obligation ought to be discharged by ATT. Fulton Ins. v. White Motor Corp., 261 Or. 206, 210, 493 P.2d 138 (1972). CWA's claim for indemnity essentially realleges the same facts as its claim for contribution. According to those allegations, both ATT and CWA could be vicariously liable to plaintiff for injuries he suffered as a result of Dymowski's defamatory statements. However, CWA has pleaded no facts from which we could infer that ATT sought from Dymowski defamatory statements about plaintiff. The indemnity complaint alleges that ATT asked Dymowsky for information about plaintiff. At best, CWA's allegations suggest that, to the extent that Dymowski acted as an agent for CWA and ATT, those entities are both vicariously liable as his principals. Accordingly, CWA has not pleaded that, as between it and ATT, any obligation owed to plaintiff should be discharged by ATT.

On appeal, judgment on third claim for relief reversed and remanded; otherwise affirmed. On cross-appeal, judgment on claim for contribution reversed; otherwise affirmed.
