Be that as it may, why would corporations that are tenants rather than landlords make decisions on that basis? Remote work saves companies a lot of money on office space.
They had a political problem with investors (why are you wasting all this money of office space that nobody is going to?) and getting people back into the office was the easiest way to take that heat off of them.
They did eventually force everyone back in the office, but I had moved on shortly before that happened.
Getting 80% of what you're paying for space you don't need is much better than getting 0%. Then you get to claim a big cost reduction this year and a big cost reduction when the lease expires and you can dump the unneeded space entirely.
Name something that can't be used at all by anyone for any purpose.
