Musk is offering an unprecedented—and uncertain—financial incentive for federal workers to resign, as part of Trump's plan to restructure the “deep state.”

The campaign by the nation’s largest federation of unions is called the Department of People Who Work for a Living, a play on Mr. Musk’s Department of Government Efficiency.

As Elon Musk and his team rip through the federal government, he is doing it all with his signature trolling, mocking his critics and targets along the way.
