all the studies what I can find that show lower productivity working from home are all based around Indian IT call centers.

I just read three studies claiming WFH reduces productivity to reply to this comment and all of them are based around Indian IT call centers.

Which is weird to me because prior to their sudden switch to IITCCs they talk about how workers perceive saving an average of 65-140 minutes on grooming and commuting for in person work in America as a productivity bonus, but upper manager perceives it as nil (because if you're commuting and you don't have to- yes its amazing, but if you're purely measuring "how much work got done between 9am and 5pm and to hell with whether you do that in office or not" then WFH is irrelevant.)

So, if it's only benefit is it makes employees happier, and on average the "productivity" gains are in morale, focus, application, and appropriate location - and at worst (in America) there's no difference (except happier employees) you really do have to be an almost literal Eberneezer Scrooge to deny them that happiness.

If you run an IT call center in India - ymmv

The main benefit is keeping commercial real estate prices up. Can't have their property investments lose money, after all.
