RIPPLE, Circuit Judge.
John Gregorich, a former research attorney for the Appellate Court of Illinois, Fourth District, brought this action under 42 U.S.C. § 1983 against Carl Lund, the former Presiding Justice of that court. Mr. Grego-rich alleged that Justice Lund fired him for engaging in union-organizing activities. Mr. Gregorich also alleged a defamation claim, based on state law, against Darryl Pratscher [412]*412and Shirley Wilgenbuseh. He alleged that their false statements proximately caused his termination. The district court denied Justice Lund’s claim of qualified immunity and retained the state tort claim under its supplemental jurisdiction. For the reasons that follow, we reverse in part, and remand.
I
BACKGROUND
A. Facts
John Gregorich began working as a staff research attorney for the Appellate Court of Uinois, Fourth District in December 1981. Prior to January 1, 1991, the court’s leave policy allowed employees to carry over unused vacation days into the next calendar year. The policy also entitled employees to compensation for unused vacation time in the event of termination. On November 26, 1990, the Illinois Supreme Court changed the leave policy. The amended policy allowed employees to carry over no more than ten days from year to year. Although the new policy became effective January 1, 1991, it applied retroactively. It thus prevented Mr. Gregorich from receiving benefits for sixty-seven of the seventy-seven vacation days he had previously accumulated.
Mr. Gregorich and his fellow research attorneys were unhappy with the new rule. In an effort to change it, Mr. Gregorich began, in February 1991, a union-organizing campaign among the research attorneys of the Fourth District. He also discussed unionization with employees in the Clerk’s Office. In April 1991, Mr. Gregorich and another research attorney signed unionization cards authorizing the Teamsters to represent them. However, the Teamsters subsequently withdrew their representation petition that had been pending before the Illinois Labor Relations Board. On November 20, 1991, Carl Lund, then the Presiding Justice of the Fourth District, discharged Mr. Gregorich on grounds of insubordination. Shirley Wilgen-busch, Research Director for the Fourth District, and Darryl Pratscher, Clerk of the Court, apparently had informed Justice Lund that Mr. Gregorich was acting in a “rude or discourteous manner.” R.l at 9. Mr. Grego-rich believed that these allegations were pre-textual and that he had been fired in retaliation for his union-organizing activities.
B. Earlier Proceedings
Mr. Gregorich filed a two-count complaint against several defendants. The first count named as defendants the Illinois Supreme Court and William Madden, the Acting Director of the Administrative Office of the Illinois Courts. It alleged that these defendants had violated the Contracts Clause, as well as Mr. Gregorich’s procedural and substantive due process rights, by changing retroactively the leave policy. Mr. Gregorich’s second count consisted of a wrongful discharge claim against Justice Lund, Ms. Wil-genbusch, and Mr. Pratscher, in their individual capacities. It also included a defamation claim against the latter two defendants. The federal claims involved in this count centered around Mr. Gregorich’s rights of free association and substantive and procedural due process. The portion of this count that articulates the First Amendment claim central to this appeal states:
By terminating plaintiffs employment with the Fourth District Appellate Court in part because of a personal desire to retaliate against plaintiff for engaging in union activities and to discourage other employees of the Fourth District Appellate Court from engaging in union activities, defendant CARL A. LUND, acting under color of State law, violated plaintiffs right of free association guaranteed by the First and Fourteenth Amendments of the United States Constitution.
R.l at 15, ¶ 62. Mr. Gregorich sought compensatory and punitive damages from the three defendants. He also sought an order of reinstatement.
The defendants filed a motion to dismiss. The district court dismissed Mr. Gregorich’s first count in its entirety.1 The court also [413]*413dismissed all of the claims in the second count except Mr. Gregorich’s First Amendment and procedural due process claims against Justice Lund and his defamation claim against Wilgenbusch and Pratscher. These remaining defendants then moved for summary judgment on the issues that had survived their motion to dismiss. The district court granted Justice Lund’s motion with respect to the procedural due process claim. It held that Mr. Gregorich was an “at will” employee. However, the court denied summary judgment on the remaining issues. First, it determined that there were genuine issues of material fact concerning whether Justice Lund discharged Mr. Gregorich in retaliation for his union-organizing activities. Assuming that Mr. Gregorich’s discharge was at least partly due to his union-organizing efforts, the district court then held that Justice Lund was not entitled to qualified immunity because the “First Amendment right of public employees to speak and assemble around union issues is well-established.” R.46 at 8-4. Likewise, the court determined that genuine issues of material fact existed with respect to the defamation claim, and chose to retain this state law claim under its supplemental jurisdiction.

DISCUSSION
A. Qualified Immunity
1.
Government officials who deprive an individual of constitutionally protected rights while acting under the color of state law are subject to personal liability for damages. See 42 U.S.C. § 1983. However, officials performing discretionary functions may avoid such liability by invoking the defense of qualified immunity, a powerful shield that insulates officials from suit as long as their conduct does not violate a “clearly established” constitutional right “of which a reasonable person would have known.” Harlow v. Fitzgerald, 457 U.S. 800, 818, 102 S.Ct. 2727, 2738, 73 L.Ed.2d 396 (1982).2 The plaintiff bears the burden of proof on the issue. McGrath v. Gillis, 44 F.3d 567, 570 (7th Cir.1995); Rakovich v. Wade, 850 F.2d 1180, 1209 (7th Cir.) (en banc), cert. denied, 488. U.S. 968, 109 S.Ct. 497, 102 L.Ed.2d 534 (1988). Accordingly, when considering a defense of qualified immunity, we inquire “whether the plaintiff has asserted a violation of a constitutional right at all,” Siegert v. Gilley, 500 U.S. 226, 232, 111 S.Ct. 1789, 1793, 114 L.Ed.2d 277 (1991), and also whether the plaintiff has demonstrated that the applicable constitutional standards were clearly established at the time in question. See Zorzi v. County of Putnam, 30 F.3d 885, 892 (7th Cir.1994) (delineating the two-part test); Rakovich, 850 F.2d at 1210. Although the plaintiff must allege the violation of a right “sufficiently particularized” to enable the district court to determine whether the defendants were on notice that their actions violated clearly established law, Anderson v. Creighton, 483 U.S. 635, 640, 107 S.Ct. 3034, 3039, 97 L.Ed.2d 523 (1987), he need not show that the very action in question has previously been held unlawful. Id.; Bakalis v. Golembeski, 35 F.3d 318, 323 (7th Cir.1994) (“[T]he right should not be defined so intricately that invariably guiding law never can be found.”) (quoting Rakovich, 850 F.2d at 1211).
Justice Lund contends that it was not clearly established at the time Mr. Gregorich was terminated that judicial research attorneys had the right to engage in union-organizing activities.3 Mr. Gregorich responds [414]*414that this right was clearly established. We review the district court’s decision to deny Justice Lund qualified immunity de novo. Bakalis, 35 F.3d at 322.
2.
To determine whether it was clearly established that Mr. Gregorieh had a right to engage in union-organizing activities, we must identify the nature of his claim and the legal standards that govern it. Mr. Gregorich’s claim is grounded in the First Amendment right of free association. See NAACP v. Alabama, 357 U.S. 449, 460, 78 S.Ct. 1163, 1170-71, 2 L.Ed.2d 1488 (1958); see also Roberts v. United States Jaycees, 468 U.S. 609, 617-18, 104 S.Ct. 3244, 3249-50, 82 L.Ed.2d 462 (1984). When a public employee alleges that he was fired in violation of his constitutional right to associate freely with others, we analyze his claim under the approach announced by the Supreme Court in Pickering v. Board of Education, 391 U.S. 563, 88 S.Ct. 1731, 20 L.Ed.2d 811 (1968) and reiterated in Connick v. Myers, 461 U.S. 138, 103 S.Ct. 1684, 75 L.Ed.2d 708 (1983). See Griffin v. Thomas, 929 F.2d 1210, 1212-14 (7th Cir.1991).4 In Pickering, the Court noted that individuals do not relinquish their First Amendment rights “to comment on matters of public interest” simply by accepting public employment. 391 U.S. at 568, 88 S.Ct. at 1734-35. However, when the State acts as an employer, it “has interests ... in regulating the speech of its employees that differ significantly from those it possesses in connection with regulation of the speech of the citizenry in general.” Id. Thus, “[t]he problem in any case is to arrive at a balance between the interests of the [public employee], as a citizen, in commenting upon matters of public concern and the interest of the State, as an employer, in promoting the efficiency of the public services it performs through its employees.” Id.; see also United States v. National Treasury Employees Union, — U.S. —, —, 115 S.Ct. 1003, 1013, 130 L.Ed.2d 964 (1995) (reiterating the standard); Connick, 461 U.S. at 142-46, 103 S.Ct. at 1687-90 (discussing Pickering, its antecedents, and its progeny). To be protected, a public employee’s expressive activity must “be on a matter of public concern” and his interest in the expression must outweigh the State’s interest in promoting the efficiency of its public services. Waters v. Churchill, — U.S. —, —, 114 S.Ct. 1878, 1884, 128 L.Ed.2d 686 (1994) (plurality opinion of O’Connor, J.) (citing Connick, 461 U.S. at 142, 103 S.Ct. at 1687; Pickering, 391 U.S. at 568, 88 S.Ct. at 1734-35).
It is important to underscore the significance that the latter part of the analysis announced in Pickering plays in qualified immunity cases. Differences in the nature of the competing interests from ease to case make it difficult for a government official to determine, in the absence of case law that is very closely analogous, whether the balance that he strikes is an appropriate accommodation of the competing individual and governmental interests. We must remember that [415]*415government officials are not expected to be prescient and are not liable for damages simply because they legitimately but mistakenly believed that the balancing of interests tipped in the State’s favor. See Hunter v. Bryant, 502 U.S. 224, 229, 112 S.Ct. 534, 537, 116 L.Ed.2d 589 (1991) (per curiam) (“The qualified immunity standard gives ample room for mistaken judgments by protecting all but the plainly incompetent or those who knowingly violate the law. This accommodation for reasonable error exists because officials should not err always on the side of caution because they fear being sued.”) (quotations and internal citation omitted). Thus, in such circumstances, ‘“the facts of the existing caselaw must closely correspond to the contested action before the defendant official is subject to liability.’ ” Rakovich v. Wade, 850 F.2d 1180, 1213 (7th Cir.1988) (en banc) (quoting Benson v. Allphin, 786 F.2d 268, 276 (7th Cir.) (Benson II), cert. denied, 479 U.S. 848, 107 S.Ct. 172, 93 L.Ed.2d 109 (1986)). Although the protection afforded the government official is indeed substantial, it is not necessary that the plaintiff produce a case that is on “all fours” with the situation at issue. As the Supreme Court said in Anderson v. Creighton, 483 U.S. 635, 640, 107 S.Ct. 3034, 3039, 97 L.Ed.2d 523 (1987), a plaintiff must allege the violation of a “sufficiently particularized” right, but need not establish that the very action in question has previously been held unlawful.
3.
We now turn to the application of these principles to the case before us. Initially, we must determine whether Mr. Gregorich’s expression touched upon a matter of public concern. “[Pjrivate speech that involves nothing more than a complaint about a change in the employee’s own duties may give rise to discipline without imposing any special burden of justification on the government employer.” National Treasury Employees Union, — U.S. at —, 115 S.Ct. at 1013. “[Wjhen a public employee speaks not as a citizen upon matters of public concern, but instead as an employee upon matters only of personal interest, absent the most unusual circumstances, a federal court is not the appropriate forum in which to review the wisdom of a personnel decision taken by a public agency allegedly in reaction to the employee’s behavior.” Connick, 461 U.S. at 147, 103 S.Ct. at 1690. The determination whether the assoeiational rights that were exercised touched upon a matter of .public concern must be based on “the content, form, and context” of his expression “as revealed by the whole record.” Connick, 461 U.S. at 147-48, 103 S.Ct. at 1690. “[O]ur cases indicate that of these three, content is the most important.” Cliff v. Board of Sch. Comm’rs, 42 F.3d 403, 409 (7th Cir.1994) (collecting eases). Mr. Gregorieh’s motive is a relevant', but not necessarily a dispositive consideration. Id. at 409-10; see Smith v. Fruin, 28 F.3d 646, 653 (7th Cir.1994) (“[W]e do not mean to suggest that merely because the employee has a personal interest in the subject of her remarks, they do not constitute speech on a matter of public concern.”), cert. denied, — U.S. —, 115 S.Ct. 735, 130 L.Ed.2d 638 (1995).
In this case, Mr. Gregorich’s activity consisted of union-organizing efforts among the judicial research attorneys of the Fourth District. Courts have recognized that such activity, in a broad sense, touches upon matters of public concern. See American Postal Workers Union v. U.S. Postal Serv., 830 F.2d 294, 301 (D.C.Cir.1987) (“The urge to unionize certainly falls within the category of expression that is ‘fairly considered as relating to any matter of political, social, or other concern to the community.’ ”) (quoting Connick, 461 U.S. at 146, 103 S.Ct. at 1689-90); cf. Boddie v. City of Columbus, 989 F.2d 745, 750 (5th Cir.1993) (noting that “much more of the range of [union] activity than the range of employee speech ... is inevitably of public concern”). However, the fact that an employee’s expression concerns a topic of public import “does not automatically” render his expression protected. Cliff, 42 F.3d at 410; see also Boals v. Gray, 775 F.2d 686, 693 (6th Cir.1985) (stating that an employee’s expression, as a matter of law, does not touch upon a matter of public concern “merely because it is union-related”). Therefore, we must probe the record to determine the “precise content, form, and context” of Mr. Gregorich’s assoeiational activity. See [416]*416Cliff, 42 F.3d at 410. After reviewing the record, we conclude that Mr. Gregorich’s efforts to promote unionization among the research attorneys of the court are, on this record, most properly characterized as touching . upon matters of public concern. Mr. Gregorich engaged in his union-organizing effort to effectuate a change in the court leave policy for the benefit of the research attorneys in the Fourth District. The point of his expression was to obtain union representation for all research attorneys. See Fruin, 28 F.3d at 651 (noting that our “public concern” inquiry “must also take into account the point of the speech in question” and examine whether it was the employee’s “point” to raise an issue because it is of public concern rather than because it is a matter of private interest) (quotation and citations omitted). Mr. Gregorich’s expression thus differs from the mostly private complaints brought solely on behalf of an individual that we recently found “entirely personal in nature,” even though they related to a subject of public import. See id. at 651-52 (determining that public employee’s complaint about second-hand smoke in the workplace was a matter of private concern); see also Cliff, 42 F.3d at 409, 411 (determining that, although issues of class size and student discipline are matters of public concern, teacher’s complaints were addressed “only to the personal impact of those issues” on her, and noting that she “was not speaking for other teachers”). Although Mr. Gregorich’s union-organizing efforts were motivated, in part, by his desire to regain his lost benefits, the record here supports a conclusion that his attempt to obtain representation for all research attorneys in the Fourth District went beyond his self-interest and made his activity subject to the requirements of Pickering and Connick.
Having determined that Mr. Gregorich’s expression involved a matter of public concern, we must now evaluate whether, at the time that Justice Lund acted, the existing case law, reasonably read, clearly established that Mr. Gregorich’s interest in union-organizing outweighed the State’s interest in the efficiency of its court system. As Mr. Grego-rich argues, it is well established, as a general proposition, that public employees have the right to associate with each other to address issues of mutual concern and of public importance.5 It is clear, however, that this right is not an absolute one and is subject to the countervailing concerns of governmental interest contemplated by Pickering and Connick. One of these interests was set forth clearly by the Supreme Court of the United States in Pickering:
It is possible to conceive of some positions in public employment in which the need for confidentiality is so great that even completely correct public statements might furnish a permissible ground for dismissal. Likewise, positions in public employment in which the relationship between superior and subordinate is of such a personal and intimate nature that certain forms of public criticism of the superior by the subordinate would seriously undermine the effectiveness of the working relationship between them can also be imagined.
391 U.S. at 570 n. 3, 88 S.Ct. at 1735 n. 3; see also Rankin v. McPherson, 483 U.S. 378, 390, 107 S.Ct. 2891, 2900, 97 L.Ed.2d 315 (1987) (“The burden of caution employees bear with respect to the words they speak will vary with the extent of authority and public accountability the employee’s role entails.”); Connick, 461 U.S. at 151, 103 S.Ct. at 1692 (“When close working relationships are essential to fulfilling public responsibilities, a wide degree of deference to the employer’s judgment is appropriate.”).
Therefore, although at the time Justice Lund acted, a public employee could associ[417]*417ate with other employees, even in a union, on matters of common interest, it was also clearly established that the associational rights of public employees were not without limitation. Among the countervailing governmental interests that have been recognized is the practical reality of governance that those with policy-making responsibilities “‘must have faithful agents.’ ” Vicksburg Firefighters Ass’n v. City of Vicksburg, 761 F.2d 1036, 1040 (5th Cir.1985) (quoting Beasley v. Food Fair, Inc., 416 U.S. 653, 660, 94 S.Ct. 2023, 2027, 40 L.Ed.2d 443 (1974)). In the usual context, this corollary principle is directed at ensuring that those who formulate and those who manage the affairs of government must have the loyalty of those to whom they must delegate that managerial authority. The application of this principle to the judiciary requires that we adjust our perspective to take into account its particular function within our governmental structure. Courts are not like most other institutions of government. Their primary role is not to formulate or to manage programs, but to decide cases. In this process, the relationship of the deci-sionmaker to those who assist in the task of deciding cases is unique. Although, in some contexts, it involves the delegation of management authority, it more often involves the sharing of intellectual confidences as the judicial officer attempts to arrive at the correct decision required by the law and the facts. The task is further complicated by the evolving working arrangements that courts across our Nation have implemented, for better or worse, to deal with the staggering case loads that have crushed all courts, but especially our state judiciaries. These new arrangements involve a variety of degrees of participation in the judicial enterprise.
In Meeks v. Grimes, 779 F.2d 417 (7th Cir.1985), we noted in the context of a political patronage firing that a judge’s chambers are perhaps “[t]he paradigm example” of an environment in which a'close working relationship is essential to perform successfully the public function. Id. at 423. Other courts and jurists have recognized that those who work closely with judicial officers must be loyal, cooperative, and responsible.6 Needless to say, confidentiality is essential. As Judge Gewin stated in Abbott v. Thetford, “every judge ... knows the importance of a cooperative and confidential relationship with staff members. The absence of either cooperation or confidentiality is disruptive and inevitably impairs the operation of any court.” 529 F.2d 695, 705 (5th Cir.) (Gewin, J., dissenting), rev’d, 534 F.2d 1101 (5th Cir.1976) (en banc) (adopting dissent), cert. denied, 430 U.S. 954, 97 S.Ct. 1598, 51 L.Ed.2d 804 (1977).7
The record in this ease establishes that, like the judicial assistants referenced in the [418]*418case law cited above, the Illinois Fourth District’s research attorneys had a close working relationship with the judges of their court. The research attorneys became privy not only to internal memoranda and draft opinions, but also to the judges’ very thought processes. See Tr. II at 16-17 (Mr. Grego-rich’s statement that he prepared research memoranda and either participated in conference discussions following oral argument or received directions on how to draft opinions from the authoring judge); Tr. IV at 26 (Justice Lund’s comment that Mr. Gregorich attended conference discussions and suggested how cases should be decided). Therefore, at the time he acted, Justice Lund was entitled to believe that the unionization of the research attorneys would threaten this delicate working relationship.8 He was not required to wait for “events to unfold to the extent that the disruption of the office and the destruction of working relationships [was] manifest” before he acted. Connick, 461 U.S. at 152, 103 S.Ct. at 1692-93.
We conclude that, at the time he acted, the state of the case law afforded Justice Lund a reasonable basis for concluding that someone with Mr. Gregorich’s responsibilities to the court had an obligation to refrain from taking such an adversarial role to the court. We emphasize that it is not necessary for us to determine in this case how the Pickering-Connick test ought to be applied in the particular circumstances of judicial-staff relationships of the court in question here or of any other court. No such question is presented to us here and the wide variety of staff arrangements now employed by various tribunals, state and federal, counsel against such a broad-stroke approach. We hold only that, at the time he acted, Justice Lund had a reasonable basis for his conclusion and therefore could invoke the protection of qualified immunity.
B. Supplemental Jurisdiction Claim
Appellants Pratscher and Wilgenbusch ask us to dismiss Mr. Gregorich’s defamation claim if we find Justice Lund entitled to qualified immunity. They note that, in the absence of any claims against Justice Lund, no federal issues will remain in this case. Mr. Gregorich argues that we should retain the defamation claim. He contends that the district court has expended substantial resources on the issue, that no further discovery is necessary, and that he might not get a fair trial in state court because he is suing state court employees.
We believe that this matter ought to be addressed by the district court. Under the governing statute, 28 U.S.C. § 1367, the district court must determine whether to exercise supplemental jurisdiction over the claim. In this case, the district court has not had an opportunity to consider whether it should retain the defamation claim in the absence of Mr. Gregorich’s federal constitutional claims. Accordingly, we remand the defamation claim for this purpose. See 28 U.S.C. § 1367(e)(3) (stating that “[t]he district court may decline to exercise supplemental jurisdiction over a claim” if it “has dismissed all claims over which it has original jurisdiction”).9
Conclusion
For the foregoing reasons, the district court’s denial of qualified immunity to Justice [419]*419Lund is reversed. He has the protection of qualified immunity against suit for damages. The supplemental claim against appellants Pratscher and Wilgenbusch is remanded for further proceedings consistent with this opinion.
REVERSED AND REMANDED.
