Elon Musk fired several dozen Twitter employees overnight on Wednesday, most of whom were engineers, two people familiar with the company's actions told Insider.
The employees fired overnight on Wednesday were informed they were being laid off for performance reasons, and were given one month of severance, one of the people said.
The termination process was similar to that experienced by previously laid-off employees, the two people said: Access to work tools and computers were cut off, and a notice of termination was sent to affected employees' personal email accounts.
