That one will be harder to enforce. They talk about terminating remote agreements, which they seem to be using interchangeably with teleework (they're not the same thing in the federal government - a remote employee is someone who works from home 100% of the time and their work station on their S5-50 is only their home, while teleworkers in non COVID times come onsite every pay period to varying degrees. I currently am onsite three days a week and WFH two days). But they mention reporting to their work stations. Which for remote employees IS their house, lol. And non-probationary union employees are going to sue and it's going to be halted for at least some time.
This actually doesn't inherently impact me, because I work under the legislative branch - Trump only has direct power over the executive branch. But I do not trust the Library not to fold like a cheap suit, so I'm bracing for it anyway. And we likely will echo the hiring freeze even though we are in DESPERATE need for numerous positions to be filled. The probationary thing for Library employees, I'm a little less concerned about. The Library knows we're understaffed, they won't get rid of probationary employees willy-nilly. Which isn't me, I'm two years past my probationary period with no plans to change positions in the next four years, but I empathize with my coworkers who are scared.
