This is LITERALLY the twitter layoffs playing out again. They fired people who had credentials and other things they needed so had to hire them back. Everything else aside why repeat the same mistakes? Just go a little slower and give agencies time to compile accurate lists of necessary employees
"Move fast and break things." /s
Then try to move fast to fix the things you just broke.
(Perhaps government tend to moves slowly for a reason: when a company breaks things customers can go to a competitor, when government breaks where can you go?)
