Probably fine - you just want to remain visible. Honestly, I think every company should encourage at least a few days a week of WFH for stress, employee health, traffic reasons - especially in IT where there is often no reason not to. You still get your face time for collab. Society would be better off. I really wish companies were incentivized to do this - especially in the bay area.

In The Netherlands this is really quite common.

+1 I know a couple of fellows from the Netherlands working 3d remote (or other jobs) + 2d in the office. Sounds perfect to me

Nice! Can we get this going in the supposed progressive, innovative SF bay area?? Please... (maybe I'm beating a dead horse :))
