I wonder how energy prices are going to change that. If someone needs to pay $1000 a month to heat their homes all day in the winter because of WFH, I can see that tipping over lots of folks to go back to the office.

If that becomes an issue, I think it's reasonable that companies will start providing extra money to remote workers to cover operating costs. After all, those same companies will need to lease less office space (meaning lower costs for space and electricity).
