The tech company I work for had been pushing hard for employees to work remotely at least 3 days per week for the last six years or so because of the obvious cost savings, ability to hire people where the cost of labor is lower, and because it was a benefit for employees that cost the company less than nothing.

They changed their tune along with all of these larger tech firms, presumably due to the commercial real estate market and maybe trying to get people to quit without having to pay severance for layoffs. Of course, they're calling it a "return" to work when they had been telling us to work remotely for over half a decade... needless to say, everyone is still pissed 8 months later, and nearly every conversation at the office includes at least one complaint about the policy. If Muskyboye ran our company, he'd have to fire a whooole lot of us.
