Elon Musk caused alarm among federal employees and drew ire over an email sent on Saturday requesting that employees summarize their work for the week, and warning on social media that a failure to do so would be taken as a resignation.

Multiple major agencies, including the FBI, State Department and Pentagon, have directed employees not to respond to Musk’s email.

Billionaire Elon Musk, who is leading Trump's Department of Government Efficiency scouring government agencies for suspected waste, delivered a warning Monday to workers on his platform X. “Starting this week, those who still fail to return to office will be placed on administrative leave,” Musk wrote.
