My employer announced that we'd be going back to the office 50% of the time and that it would start in August. Management was in the office as of this month. This was announced in April/May.
Several people quit because of this. Two people on my team (we have about 8 people). I've had to train 2 new people by myself for 2 weeks each time, and I'm still their “go to” for everything, so I'm essentially doing my work and theirs for a while.
Yesterday, we had a meeting with every single colleague in the company. The first thing they announce is that we're no longer going back to the office because of “inflation and gas prices” (aka everyone is quitting so we had to do something).
The people who quit had worked there over 20 years and would have stayed if we had a permanent work from home (like we now have) and I had to learn a completely new jurisdiction with zero training because they quit.
