It will come down to perks and worker desires. I live less than 15 minute bike ride from my office and only go in twice a week. I notice my electric bull is higher but worth the flexibility. I would move to another position offering flexibility if my employer foolishly and selfishly started requiring full time in office... I can guarantee all that my productivity would not improve. That being said I was a hybrid worker before the pandemic so I already enjoyed the flexible lifestyle and wouldnt have changed anyway. I am not alone in this and companies need us more than we need them.
