Another factor that I didn't consider is that there was basically nothing to do but work in many places - most things fun were either banned/shut down, or unattractive because they came with the implied threat of catching COVID. This includes vacation. I bet once recovery sets in, a lot of saved-up vacation time gets used at once, especially in countries and companies where significant amounts of vacation can be banked.

But you can begin to see some limits of remote work. Obviously military units shouldn't be training remotely. The bonding is too important.
Our company was quite restrictive of working from home previously but after last year seeing that we had our most productive year ever, things loosened up a lot.
Curious, what are the outcomes?
