I dont think that the number of individuals getting re-hired is going to be anywhere near as large as you think that it will Kodiak. I also dont think it is quite as random as what is being portrayed. Looks to me like they are doing their best to eliminate all the jobs that Biden magically created in his last 2 yrs in office. Obviously, they were not needed during Trump's first term so they shouldnt be needed now. Especially with the pandemic being over. According to the Associated Press, it looks like 98% of the loss is made up of short timers/recent hires. Found this current tally from AP (Numbers from AP's DOGE article that was current as of 4 days ago)

Office of Personnel Mgmt states that 75,000 have elected to take the retirement offer/severance package option originally offered
Dept of VA 1,000 probationary with less than 2 yrs service
Dept of Defense 5,400 probationary next week Est reduction in civilian workforce of 5-8% upcoming
Dept of Education 39 (more to come once bogus injunction is lifted)
Dept of Energy 350 probationary employees
IRS no definitive number given only that it will be in the 1,000's
Dept of Health and Human Services 5,000 probationary employees
CDC 1300 probationary employees
National Park Service released approx 1,000 new hires but reinstating 5,000 seasonal employees
NIH, FDA, Centers for Medicare and Medicaid all probationary employees. No number given
DHS 405 probationary employees
FEMA 200 probationary employees
Consumer Financial Protection Bureau Ordered to stop work. Entire agency to be disbanded # unknown
Dept of Agriculture 2000 probationary employees (all non-fire related)
17 Inspector Generals (for not doing their jobs)
USAID ???? I'm assuming number unknown at this time.
DOJ ????
State Dept ????

After they get done removing all jobs associated with Biden's willful expansion of the govt bureaucracy and DEI jobs program, then they need to move into eliminating the redundant functions, redundant jobs, redundant agencies, redundant duties, restructuring, reorganizing, and eliminating multiple agencies and departments to streamline services. This should be done on a competency and merit basis with input from dept heads and supervisors being retained.
