People blow it off as not necessary, but
there are a lot of irresponsible people out there fukking around at home and not getting their work done. Dudes on here were BRAGGING about fukking around all day and just checking in for meetings
I'm not a manager, but I've had some project management experience. Managers are trying to keep track of progress to report to higher ups and if someone's sitting at home pretending it's all hunky dory, they're going to want people back on site.
I love WFH, but I'm starting to worry it won't work long term.
EDIT: I don't know what all industries are like but my immediate boss I can see how much running around he has to do managing projects. He might not understand as well as devs, but he's taking the time to try and communicate issues between teams.
