Federal workers began receiving emails Saturday asking them to explain what work they did last week, as Elon Musk announced that “failure to respond will be taken as a resignation.”

Musk caused alarm among federal employees over an email sent on Saturday requesting that employees summarize their work.

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.
