If say you choose to work from home and then you find out your coworkers working in office get more wage increase or promotion than you do, would you be OK with it?
“Not going into the office” != “never seeing coworkers face to face.” Being remote has forced our team to be more proactive about seeing one another and so we’ve ended up socializing more than we ever did at the office. It’s easy to fall into the trap of not doing anything other than working chat and water cooler conversations and never actually socializing because “we see each other every day.”
Also, they can always link the difference to race/gender etc. Say, if there are more women or racial minorities chose option A, and then option A leads to less wage increases, then the company will be in trouble.
