You're saying companies trade out having open offices for perks. I'm saying I don't care about those perks, and would rather have less perks and 4 walls.
Our team has some middle-aged people who do a strict a 9 to 5 and that is perfectly fine. We never expect them to stay around for board games or whatever.
But that doesn't mean the rest of us can't hang out with our colleagues.
I worked for a SV company with a ping pong table, video games, board games etc.
If you don't participate you're seen as "not a team player"... It's the same with lunches etc. They want you at the office as much as they can get/keep you there, and now they're doing their best to create "inclusive social environments".
It creates an "in" and an "out" crowd, and if someone decides you haven't hit your monthly Go Karting/drinking event/fancy dinner quotas you're the office outcast. Managers love this because it's all under the guise of "family" or "team building" etc. and it gives them a totally arbitrary metric to nickle and dime someone on.
In other words, it turns what should be a recreational activity into a job requirement? While I haven't experienced that myself (but then, I don't work in SV), if I did, it would make me actively angry to have a job requirement that did nothing but take away from accomplishing what I was hired to accomplish.
Family does not play into this picture.
