Elon Musk plans to eliminate about 3,700 jobs at Twitter, or half of the social media company’s workforce, in a bid to drive down costs following his $44 billion acquisition, according to people with knowledge of the matter.

Twitter’s new owner aims to inform affected staffers Friday, said the people, who requested anonymity discussing nonpublic plans. Musk also intends to reverse the company’s existing work-from-anywhere policy, asking remaining employees to report to offices — though some exceptions could be made, the people said.

Musk and a team of advisers have been weighing a range of scenarios for job cuts and other policy changes at San Francisco-based Twitter, the people said, adding that the terms of the headcount reduction could still change. In one scenario being considered, laid off workers will be offered 60 days’ worth of severance pay, two of the people said.
