Atlassian Fired an Engineer for a Slack Message. A Federal Judge Just Ordered Them to Hire Her Back.

"What's up Outragers, just dialing in from my NBA team's headquarters to yell at the people whose careers I've just pummeled."
— Denise Unterwurzacher, Senior SRE, Atlassian · Company Slack channel, June 2023

The story

Atlassian, maker of Jira and Confluence, ran a company-wide "Ask Me Anything" video call in June 2023 to explain a restructuring that included layoffs and title demotions. CEO Mike Cannon-Brookes dialed in from the headquarters of the Utah Jazz, the NBA team he co-owns.

After the call, employees migrated to a company Slack channel called "Outrage Notification" (a play on "outage notification"). Senior site reliability engineer Denise Unterwurzacher posted the message that would become a federal exhibit: a sarcastic parody of the CEO's remarks from the comfort of his NBA franchise while colleagues worried about their livelihoods.

Days later, Atlassian fired her. The termination cited a "pattern of acrimonious communications" and a "gratuitous personal attack" against the CEO. Unterwurzacher had previously received write-ups for similar internal criticisms dating back to 2019.

The NLRB's General Counsel filed a complaint. The case went to hearing in Austin.

The exposure

Administrative Law Judge Susannah Merritt ruled in early July 2026 that Atlassian violated federal labor law. The termination constituted retaliation for protected concerted activity under Section 7 of the National Labor Relations Act.

The judge found that other employees posted comparable remarks in the same Slack channel on the same day. None were disciplined. The selective enforcement gutted Atlassian's claim that the issue was "behavior, not content."

The damage extended well beyond the termination itself. Two versions of the severance agreement offered to Unterwurzacher contained confidentiality and nondisparagement clauses the judge found unlawfully broad under McLaren Macomb (2023). Four rules in Atlassian's internal Community Guidelines were struck down as unlawfully vague under Stericycle (2023) and ordered rescinded.

The remedy: reinstatement with full back pay and interest, expungement of all disciplinary records, and a written notice posted to every employee. Atlassian's own stated company value, "Open Company, No Bullshit," was cited throughout the proceeding as evidence that the company's culture invited exactly the kind of candor it then punished.

Before you hit send

The employee's Slack message was blunt, sarcastic, and directed at the CEO by name. Under Section 7, it was protected. Criticizing restructuring decisions, including doing so sarcastically, publicly, and while the CEO is listening, constitutes concerted activity about working conditions.

Three written documents generated all the exposure in this case: the termination notice, the severance agreement, and the Community Guidelines. The employee's Slack message generated none.

Whoever drafted that termination notice needed a five-second intervention: this employee's criticism of restructuring decisions may constitute protected concerted activity under NLRA Section 7. Terminating for this conduct creates unfair labor practice exposure—consult labor counsel before proceeding. Five seconds. That is the distance between a defensible management decision and an order to reinstate with back pay.
