I've said it before, I don't like working from home. But I dislike working for underpaying petty feudal overlords with garbage tech stacks and mediocre management even more.
I know what my local market is like, and there's plenty of remote companies happy to outcompete them. So that's what I'll do.
That said:
Apparently showing that you can continue to deliver at a high standard, remotely, for two years is not an indicator that you will be able to work like that always.
In reality, I know that Google's own metrics showed marked decline in productivity during that period. I witnessed it first hand and saw all sorts of deadlines slip and things get cancelled.
Whether that was due to WFH or people dealing also with having kids and spouses at home -- and the fact that the whole world was seemingly falling apart around them -- I don't know. I know I didn't cope well with it.
But also, I think those kinds of Big Companies proved themselves absolutely woefully incompetent in adapting. They didn't handle it well. At least my team didn't.
