OPINION
This case tests the bounds of a public employer’s right to discharge or demote an employee for taking action on a matter of public concern. Under the balancing test in Pickering v. Board of Education of Township High School District 205, 391 U.S. 563, 568, 88 S.Ct. 1731, 20 L.Ed.2d 811 (1968), we have long given public employers significant discretion to discipline employees if their conduct disrupts the workplace. That discretion, however, has never been unfettered. An employer may not interfere with an employee’s First Amendment rights unless there is evidence that the employee’s actions have actually disrupted the workplace or are reasonably likely to do so in the future. Simply saying that there has been or will be disruption, without supporting evidence, is not enough. In the face of Pickering, the “because I said so” approach is insufficient to establish a reasonable prediction of disruption, let alone actual disruption.
Kathleen Nichols, a former employee of the Washoe County School District (“District”), was forced to take early retirement after attending a school board meeting at which her boss was fired. The District claimed it was concerned that her association with her former boss would create conflicts in the office. Viewing the record in the light most favorable to Nichols, however, it appears the triggering factor in the District’s action was simply Nichols’s decision to sit next to her boss at the public board meeting, without even speaking to him. Because the District produced no evidence that Nichols’s association with her boss actually disrupted the office or her performance, or reasonably threatened to cause future disruption, the District has failed to show that its interests in workplace efficiency outweigh Nichols’s First Amendment interests. Accordingly, we reverse the district court’s grant of summary judgment in favor of the District.
I. Background
Nichols worked for the District for nine years. During her last six years, she served as the administrative assistant to Jeffrey Blanck, the District’s General Counsel. In this position, Nichols reported directly to Blanck and had a variety of responsibilities related to the District’s legal matters, including providing litigation support and managing case files. Nichols and Blanck were friends and would sometimes socialize outside the office.
In late 2003, a dispute developed between Blanck and James Hager, the District Superintendent, over allegations by Blanck that Hager had misused District funds. On January 16, 2004, Blanck was suspended as General Counsel. Laura Dancer, the head of Human Resources for the District, told Nichols about Blanck’s *932suspension and instructed her that she should no longer take direction from Blanck, but only from Hager or Dancer.
After Blanck was suspended, Nichols was transferred to a temporary position in the Human Resources department, while decisions were made about the future of the General Counsel’s office. She got along well with her colleagues in Human Resources and there were no reports of any problems with her work.
On March 23, 2004, the Board of Trustees of the District held a meeting to discuss a variety of matters, including Blanck’s employment. The day before the meeting, Dancer informed Nichols that she would be returned to her position in the General Counsel’s office, regardless of whether Blanck was fired.
The March 23 meeting was an open, public meeting. Nichols attended because a friend of hers was receiving an award and because she wanted to see if Blanck would keep his job. Nichols sat next to Blanck at the meeting, but did not speak to him. At the meeting, the Board announced that Blanck would not be retained as General Counsel.
The next day, Dancer called Nichols into her office and told her that she would not be returned to the General Counsel’s office because she had attended the March 23 meeting and there were questions about her loyalty to the District. Dancer told Nichols that she could remain in Human Resources, where her salary would be frozen, or take early retirement. Nichols chose to retire early.
Following her retirement, Nichols filed a lawsuit under 42 U.S.C. § 1983 against Dancer, Hager and the District (eollectively, the “District”), claiming that she had been demoted in retaliation for exercising her First Amendment rights by attending the March 23 meeting and sitting next to Blanck. The District moved for summary judgment, arguing that Nichols’s conduct was not entitled to First Amendment protection because it was not related to a matter of public concern and because the District’s interests in an efficient workplace outweighed Nichols’s First Amendment interests. The district court granted the District’s motion, holding that the District’s efficiency interests were greater than Nichols’s interest in free association.
II. Analysis
To prevail on her First Amendment claim, Nichols must show that her association with Blanck was constitutionally protected and that it was a substantial and motivating factor in her transfer from the General Counsel’s office. Brewster v. Bd. of Educ. of Lynwood Unified Sch. Dist., 149 F.3d 971, 978 (9th Cir.1998). Only the first part of this test — whether Nichols’s conduct is protected by the First Amendment — is at issue in this appeal.1
It is by now black letter law that “a state cannot condition public employment on a basis that infringes the employee’s constitutionally protected interest in freedom of expression.” Connick v. Myers, 461 U.S. 138, 142, 103 S.Ct. 1684, 75 L.Ed.2d 708 (1983). At the same time, however, public employees such as Nichols do not enjoy an absolute right to free speech. See Brewster, 149 F.3d at 978. Rather, as the Supreme Court acknowledged decades ago, “the State has interests as an employer in regulating the *933speech of its employees that differ significantly from those it possesses in connection with regulation of the speech of the citizenry in general.” Pickering, 391 U.S. at 568, 88 S.Ct. 1731. To determine whether Nichols’s conduct receives First Amendment protection, we must engage in the Pickering balancing test,2 which requires us to seek “a balance between the interests of [Nichols], as a citizen, in commenting upon matters of public concern and the interest of the [District], as an employer, in promoting the efficiency of the public services it performs through its employees.”3 Id.
In striking the Pickering balance, we “must give [public] employers wide discretion and control over the management of their personnel and internal affairs,” including “the prerogative to remove employees whose conduct hinders efficient operation and to do so with dispatch.” Brewster, 149 F.3d at 979 (internal citation and quotation marks omitted). In broad terms, Pickering favors the employer if the employee’s conduct “impairs discipline by superiors or harmony among co-workers, has a detrimental impact on close working relationships for which personal loyalty and confidence are necessary, or impedes the performance of the [employee’s] duties or interferes with the regular operation of the enterprise.” Rankin v. McPherson, 483 U.S. 378, 388, 107 S.Ct. 2891, 97 L.Ed.2d 315 (1987); see also Gilbrook v. City of Westminster, 177 F.3d 839, 867-68 (9th Cir.1999). The employer need not establish that the employee’s conduct actually disrupted the workplace— “reasonable predictions of disruption” are sufficient. Brewster, 149 F.3d at 979 (internal citation and quotation marks omitted).
The fact that public employers have significant leeway to regulate employee speech, however, does not mean that their discretion is without bounds. While acknowledging the importance of workplace efficiency, we have never given public employers carte blanche to retaliate against employees whose conduct does not reasonably threaten to disrupt operations. See Brewster, 149 F.3d at 979 (evidence of actual disruption or “reasonable predictions of disruption” are required (internal citation and quotation marks omitted)) (emphasis added). Pickering, after all, is a balancing test—it requires us to weigh efficiency concerns against an employee’s legitimate interest in engaging on matters of public concern. See Pickering, 391 U.S. at 568, 88 S.Ct. 1731. We cannot abdicate this responsibility simply because an employer raises the specter of disruption.
Although we accord significant weight to an employer’s reasonable judgments about the workplace, an employer *934cannot prevail under Pickering based on mere speculation that an employee’s conduct will cause disruption. See Nunez v. Davis, 169 F.3d 1222, 1229 (9th Cir.1999) (“[R]eal, not imagined, disruption is required.”) (internal citation and quotation marks omitted). It is no surprise, then, that other circuits have determined that a disruption claim must be supported by some evidence, not rank speculation or bald allegation. See Gustafson v. Jones, 290 F.3d 895, 909 (7th Cir.2002) (“Pickering balancing is not an exercise in judicial speculation.”); Kinney v. Weaver, 367 F.3d 337, 363 (5th Cir.2004) (“[EJngaging in Pickering balancing is not like performing rational basis review, where we uphold government action as long as there is some imaginable legitimate basis for it.”). An employer must provide some evidence by which we can measure whether its claims of disruption are reasonable. If the evidence establishes that the employer’s interests are reasonably threatened, then will we tip the Pickering scales in its favor.
Because the District moved for summary judgment, we must view the record in the light most favorable to Nichols. See Robinson v. York, 566 F.3d 817, 821 (9th Cir.2009). Doing so, we find no evidence to suggest that Nichols’s association with Blanck actually disrupted the District’s operations.4 Nor is there anything in the record to the effect that their association interfered with Nichols’s job performance or negatively affected her relationships with Dancer or other co-workers. Nichols testified that she got along well with Dancer and her colleagues in the human resources department and the record does not reveal otherwise. See Nunez, 169 F.3d at 1229 (“A public employer cannot claim disruption of a close personal relationship to cover up animus toward an employee’s speech and a desire to silence the employee.”). Indeed, nothing supports the dissent’s suggestion that Nichols had a “confidential relationship” with Blanck or that any of their “continued communication” was the basis for any claim of disruption.5 See Dissent at 936.
Of course, the District is not required to establish actual disruption, but only reasonable predictions of future disruption. That the District may rely on the possibility of future disruption, however, does not *935mean that we will rubberstamp its decision based on an assertion that Nichols’s association with Blanck might have caused problems or been a reflection of the level of her loyalty to the District. The District did not produce evidence to establish that its predictions of disruption or disloyalty are anything but speculation. The District asserts that Nichols’s association with Blanck would have created a conflict because, in the General Counsel’s office, Nichols would have had access to information about a wrongful termination lawsuit that Blanck filed against the District after he was fired. In the absence of any evidence of disloyalty, it is pure speculation to claim that Nichols was likely — or even inclined — to divulge this information to Blanck or otherwise misuse it.6 The record offers no support for the claim that Nichols’s contact with Blanck threatened to disrupt the District’s operations, or that Nichols was predisposed to cause problems down the road. The District’s bare assertions of future conflict are insufficient to carry the day at the summary judgment stage. See Lindsey v. City of Orrick, 491 F.3d 892, 900 (8th Cir.2007) (“Mere allegations the speech disrupted the workplace or affected morale, without evidentiary support, are insufficient.”); Kinney, 367 F.3d at 363 (“We do not let the governmental defendant prevail, on summary judgment, by relying on interests that, viewing the record in the non-movant’s favor, are not reasonably threatened in the case.”) (emphasis in original); Andersen v. McCotter, 100 F.3d 723, 729 (10th Cir.1996) (employer failed to “provide evidence sufficient to assess the character and weight of [its] interests”).
The long and short of it is that Nichols is an employee caught in the crossfire between the District and her former boss. In the absence of any evidence that she was disloyal, had disrupted the office or was even reasonably likely to cause disruption in the future — and, viewing the record in the light most favorable to Nichols, there is no such evidence — the District sanctioned her for simply showing up at a public meeting and sitting next to Blanck. Even under the deferential Pickering test, this allegation is insufficient to tip the balance in the District’s favor. We conclude that the District failed to produce adequate evidence to establish, as a matter of law, that its interests in workplace efficiency outweighed Nichols’s First Amendment interest in associating with Blanck. At a minimum, material questions of fact remain on this point. See Robinson, 566 F.3d at 825 (“Where ... ‘there are underlying factual issues regarding the extent of office disruption’, it is proper to deny a motion for summary judgment” (quoting Roth v. Veteran’s Admin, of Gov’t of U.S., 856 F.2d 1401, 1408 (9th Cir.1988)). Accordingly, we reverse the grant of sum*936mary judgment in the District’s favor and remand to the district court for further proceedings consistent with this opinion.
