(The Hill) — Elon Musk, special advisor to President Trump, warned federal employees on Saturday of a new policy requiring them to detail their work efforts via email in order to keep their jobs.

“Consistent with President @realDonaldTrump’s instructions, all federal employees will shortly receive an email requesting to understand what they got done last week,” Musk wrote in a Saturday afternoon post.

“Failure to respond will be taken as a resignation,” he added.

The tech giant did not outline any additional details on the public platform, however, The Hill reviewed a copy of the message sent to federal employees. 

“Please reply to this email with approx. 5 bullet points of what you accomplished last week and cc your manager. Please do not send any classified information, links or attachments,” the email read. 

“Deadline is Monday at 11:59pmEST.”

Musk’s post comes as a slew of executive orders are changing the landscape of the federal government.

Members of Congress have alleged that recent internal orders have restricted employees at top agencies from speaking to lawmakers or outlining the details of internal probes from the Department of Government Efficiency.

Among President Trump’s recent executive actions are those that have removed thousands of probationary status workers from federal agencies and intend to ban diversity, equity and inclusion efforts at all levels. 

The American Federation of Government Employees responded to the email sent to federal employees with a statement expressing frustration.

“Once again, Elon Musk and the Trump Administration have shown their utter disdain for federal employees and the critical services they provide to the American people. It is cruel and disrespectful to hundreds of thousands of veterans who are wearing their second uniform in the civil service to be forced to justify their job duties to this out-of-touch, privileged, unelected billionaire who has never performed one single hour of honest public service in his life,” the group wrote.

“AFGE will challenge any unlawful terminations of our members and federal employees across the country.”
