My 5k+ person tech employer has basically said anyone who wants to work remote will be able to. The argument seems to be that it won't be possible to competitively hire/retain if remote is not an option.
The 100K+ person bank that I work at also offered new flexible working arrangements. Pretty much comes down to your team and manager, but I ended up with a full-time work from home position. Others do a few days in office, then the rest WFH. I think they acknowledged that most people were more happier when working from home, and that productivity didn't go down over the last year.
But then I also read a news article about how my company was giving up 3 floors in their Asia HQ, which ended up being close to US$ 1 million a month. So money is definitely involved as well.
