That's very antagonistic? Statistics show otherwise. WOH employees spend more time on task and produce more. Throwing around speculation and bias is unproductive. Just more FUD.
Which statistics? At least for my employer, it was reported that productivity dropped across the board and I certainly feel that's true for me personally.
It's never really been put to the test, though. Most companies have been working in offices because they've always been working in offices. Prior to fast internet availability there was no other choice. It's a deep rooted part of culture and it usually takes a much longer time for these things to change even though it might make sense. In Australia they celebrate Christmas in Summer. That makes no sense, but it's not going to change any time soon. The pandemic has accelerated this change that probably wouldn't have happened for decades otherwise.
I know you don't like your manager, but trust me: it's not true that 100% of managers on this planet are idiots running on preconceived notions and FUD.
If work from home was profitable than some company out there would have made bank already.
Work from home doesn't work because humans can't context-switch too well.
Again, that argument is more FUD. It's predicated on 'if people were rational'. Consider this: I've written three comments trying to rebut an argument based on nothing but FUD. If people were rational, there would be references to studies or statistics to rebut, but no I have only tired lazy arguments to try and refute.
To address that latest FUD, working from an office is worse in the interruption aspect. At home I can make draconian rules about when I'm interrupted. Not so in an office.
WOF doesn't always work, but it can work and very effectively. Way more often than folks are willing to try it.
And consider: this argument is from somebody who has worked from home for most of their career. How often have you tried it?
