In what might be the biggest “Oops” moment in corporate history, an HR department accidentally sent a termination notice to every single employee, including the CEO, triggering mass confusion, mild panic, and an unforgettable day on Slack.

The workplace disaster unfolded after a Reddit user shared the tale on r/Wellthatsucks, explaining that HR was testing a new “offboarding automation tool” — the kind that sends exit emails to employees who are leaving.

Except… someone forgot to flip the switch from test mode to live mode. Within seconds, around 300 employees received an ominous email that began, “Your last working day is effective immediately.”

The office reaction? Utter bedlam. “Slack went nuclear,” the original poster wrote. “One manager literally asked, ‘Should I start packing?’”

Minutes later, the IT team had to step in like firefighters at a code-red meltdown, blasting a company-wide message in all caps: “NO ONE IS FIRED. PLEASE DO NOT TURN IN YOUR BADGES.” 

The internet, of course, found it hilarious. The post went viral, pulling in over 40,000 upvotes and a flood of sympathetic (and savage) comments.

One Redditor quipped, “That one guy who just thumbs it up was like, ‘Damn well ok, guess I’m fired.’” Another wrote, “Honestly, I’ve had jobs where I would’ve just packed my stuff and said, ‘Fair enough.’”

And then came the line that summed up corporate absurdity everywhere: “Any company that needs a mass termination tool is doomed to fail.”

Someone else added: “Nobody is fired, I repeat, nobody is fired. Except you, Bob. Come see me in my office.”

For now, everyone’s jobs are safe — except perhaps for the poor HR intern who pressed send on the apocalypse.
