I think the reason why middle (and upper) management hates WFH is not the culture. It’s not the accountability of its workers. Its the fact that it opens the market.
To me, antiwork means anti-bad management. Businesses have relied on momentum and barriers to entry. They can abuse workers because it’s tough to change jobs. Now it’s easier, and they’re being held accountable. That, of course, is problematic for many reasons (favors remote-able jobs, etc), and this isn’t an endorsement. It’s just an observation. In fact, as Amazon and Uber provide an alternative… they naturally become a 5th column. But in any case what we see right now is a rise in workers’ rights overall.
In any case, the Internet’s officially in charge now.
