As people have probably already heard, Elon Musk sent an email to 2 million federal employees last week through the Office of Personnel Management, saying they needed to list 5 accomplishments from the prior week by the end of today (Monday 24th). He then said that failing to reply would be taken as resignation.
The Pentagon, State Department, Justice Department, FBI, NIH, Energy Department, DHS, HHS, Office of the DNI, NOAA and NSA all instructed their staff that they either shouldn't respond to it, or didn't need to respond to it. Dept of Transport said staff should respond. Lawyers have sued in federal court in California.
Will be interesting to see if anything actually happens, or if this was all just some pathetic kind of performative theatre. I suspect the latter... or that Musk will pretend it was just theatre when non-compliance is overwhelming.
