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.

Musk initially said the request was a 'very basic pulse check,' but now says it will root out 'non-existent people or...dead people' who are collecting paychecks. Several agencies are telling employees to ignore the email for now.

U.S. Treasury employees may need to respond now to Musk’s email, but leaders at other agencies have told their workers to ignore it altogether, according to CNN. Decisionmakers at the Pentagon, the Department of Homeland Security, the Department of Energy, and the Department of Justice have told employees to just not respond to Musk’s demands.
