Re: Measures
"Can it be possible to isolate the change in outputs specifically due to location of employees?"
I don't think the employers that want people back and firmly shackled to a desk in a downtown high rise will want to look at that. I know some people enjoy busy dense cities, but I am firmly in the other camp. There's no way I could afford to own my own home in most of those places, much less have it paid off. I also don't like an endless parade of people wanting to sell me something going door to door which doesn't happen nearly as often in a small town where the houses can be spaced quite a distance from each other. Not that I answer the door when I'm not expecting somebody.
Being happy where I am and not traveling to a place I don't like is likely to be a factor in my output. Not having to take deep breaths and bring my mood back down to ground level means I can get to being productive much quicker and not start ramping up the "commute home dread" sometime mid-afternoon. Buzzing around town is perfectly fine. I know many of the shop owners/employees, traffic isn't an issue and there's the pleasant chance of running into somebody I know and having a chat, getting a dinner invite, that sort of thing.
