It's hilarious how many people are religious about WFH. Like arguing you must not have a social life or you are extraverted if you need to be in the office.... Some people like the office some don't. At the end of the day if people working from home get more done, they'll be allowed to do so. But I've seen a lot of schedules slip the last year, most likely it's because of the pandemic, but maybe it's the ability to come to a space and focus. In a year if companies that remain WFH get more done, then that'll become the norm, but if people who WFH get less done, more restrictions will be added. Instead of being a zealot about it, go prove it works for you.
