In the midst of Elon Musk and Donald Trump’s efforts to improve the efficiency of the government, federal employees have been given an ultimatum: they must answer to an email or they would be considered to have quit.

Musk, who is now a special government employee and is running the Department of Government Efficiency (DOGE) alongside Vivek Ramaswamy, made the announcement that beginning on Monday at 11:59 p.m. Eastern Time, all federal employees are required to provide a summary of their weekly accomplishments. On Twitter, he issued a strict warning that failure to react will be interpreted as a resignation.
