Or massages, child care, game rooms, or any of the other ridiculous perks. The company could start rolling those back if enough people wfh.
There are enough studies on why those campuses are designed that way. The convenience is designed at making sure you spend more time at work.
I can absolutely attest to this. Since WFH, at least a couple of times a week or on the weekend I'll have little a-ha moments or things I want to test. I reason I'll just quickly log in to my work laptop to play around for a few minutes... that often turns into a couple of hours. It usually results in the problem being solved and me riding the 'high' for the rest of the evening/weekend.
That never would have happened without WFH. I'm not even complaining because I'm doing it on my own terms and am in no way obligated to do it.
