Twitter employees will be notified by email by 9 a.m. Pacific Standard Time on Friday whether they will be laid off, according to a communication sent out to all Twitter employees on Thursday evening. It was the first employee-wide communication since Elon Musk closed his takeover of the social network a week ago.

In an unsigned email, Twitter wrote: “In an effort to place Twitter on a healthy path, we will go through the difficult process of reducing our global workforce on Friday. We recognize that this will impact a number of individuals who have made valuable contributions to Twitter but this action is unfortunately necessary to ensure the company’s success moving forward.”
