Find me a company deeply invested in office real estate (in particular, expecting a return on that real estate), and I’ll show you a company against remote work.
The real detriments don’t exist. True, I have met workers that don’t like remote work: companies have latched on to those people as an excuse to continue what is otherwise an entirely transparent narrative.
If anything I gain productivity by working from home. I see companies that don’t support that kind of work as entirely being behind the curve.
