Now that the preliminary injunction was lifted (judge ruled plaintiffs didn't have standing), the Administration has apparently closed the books on their offer. It appears about 75K federal workers accepted the offer, give or take.

With a civilian federal workforce of about 2.3 million, that's below the 5-10% range that Musk had given as their expectation. A little more than 3%. What makes that really bad, though, is that the normal departure rate for federal workers (people resigning or retiring) is a little over 5% per year. Which means that the number of people taking deferred retirement (staying on the payroll for 7-8 months before leaving) is probably a little bit lower than the number of people who would have left the federal government over that eight months anyway.

Had there been more uptake, it would have been likely that this would have resulted in some reduced personnel expenditure for the government. But at this level, there's now a very good chance that the program did little more than give a paid vacation to all the people who would have left in the next 7-8 months anyway.
