A very common reason is because you're not clerical staff, you're courtiers. The bosses want an office with people running around hurriedly doing busy stuff, which accounts for a lot of the bullshit jobs that workers are assigned, not that they need to be done, but to serve as a Tiger Repellant Rock. Or the bear patrol, which is from the same Simpsons episode.

A more conscious answer is that offices had been leased out for years at a time, and leaving them empty would mean they go to waste. While this means workers time is wasted (commute, prepping lunch out etc.) they don't care about that as much.

When RTO orders became required (RTO or be laid off / RTO or get reassignment) that was part of the ownership class reasserting their dominance over a working class who was suddenly in demand after the lockdown and post-epidemic period. It was notable that even the Democratic officials were glad to memory-hole all the progressive programs that manifested to facilitate business during the lockdown. In fact, the telecommute controversy became the keystone issue, since workers learned they were happier and did better work at home. But the boss wanted to see them labor in their cubicle.

We suck at retaining class consciousness, or the super-giant conservative propaganda machine is really good at suppressing it. Seriously, FOX News and OAN are poison.
