Employees are getting ready for major layoffs at Twitter now that Elon Musk took over.

Musk is overhauling the social media platform, making big changes.

He sent a letter to employees that multiple people were losing their jobs. By early Friday, employees were already tweeting that they were locked out of their computer work accounts. 

The email sent to staff said job reductions were “necessary to ensure the company’s success moving forward.”

According to Bloomberg News, half the workforce of Twitter, about 3,700 employees, could be let go.  Musk has already fired top executives at Twitter, including the Chief Executive Officer, Parag Agrawal, on the first day he took ownership. 

He also axed the board of directors and made himself the only board member. 

He shockingly made himself the chief moderator, for now anyway.

There is a federal and California statute, the Worker Adjustment and Retraining Notification Act, that says that employers with at least 100 workers have to announce layoffs of 500 or more employees within 60 days of the action.

As of Thursday, no public announcement had been made, as per Barry C. White, a spokesperson for California’s Employment Development Department.

A Twitter employee who was laid off, and three others who were locked out of their accounts, filed a class action lawsuit in a San Francisco court on Thursday, saying that Twitter has violated the law by not abiding by the requirement for a 60-day in advance public announcement of the layoffs.

It is uncertain if the lawsuit will have any merit, as Musk has apparently agreed to continue salaries to laid-off employees for a period of time.
