Twitter is getting sued as it gears up for mass layoffs, with lawsuit saying company didn't give employees enough notice of job cuts

• A class-action lawsuit was filed against Twitter in San Francisco federal court.
• The lawsuit is over Twitter's plan to lay off thousands of employees, court papers show.

A class-action lawsuit filed on Thursday in San Francisco federal court says Twitter's plan to lay off thousands of employees is in violation of federal and California law, court papers obtained by Insider show.

The lawsuit — filed by attorney Shannon Liss-Riordan — is asking the court to issue an order requiring Twitter to obey the WARN Act and to restrict the company from soliciting employees to sign documents that could give up their right to participate in litigation.

The WARN Act, or the Worker Adjustment and Retraining Notification Act, is a federal law that requires businesses with 100 or more employees to give 60 days advance notice of mass layoffs or other work disruptions.

Liss-Riordan and Twitter did not immediately respond to Insider's requests for comment sent outside business hours.

On Thursday, Twitter employees received an email from the company confirming that there would be layoffs on Friday, Insider's Kali Hays reported. Around 3,700 Twitter employees are expected to be laid off.

Some Twitter employees began losing access to work platforms shortly after Musk told them to expect layoffs to begin the following day, Insider reported.

"I got logged off company Gmail and slack in the evening along with my teammates. No communication or notice whatsoever," a staffer wrote in a LinkedIn post late on Thursday.

Another employee wrote on LinkedIn: "Just got remotely logged out of my company laptop and removed from Twitter Slack. So sad it had to end this way."

"I had the pleasure of working with amazing Tweeps who showed incredible resilience and compassion during this entire ordeal. This isn't what we asked for but we made the best of it," a third staffer wrote on LinkedIn.
