Honestly, I think if that's the general consensus, then who gives a shit about productivity?
Employees, especially in America already have almost no bargaining power, literally no statute mandated vacation, terrible worker protections like "exempt (from overtime pay) employees" which I'm sure almost everyone on this board falls under. So literally the more hours they make you work, the less per hour you earn. How that one got passed congress without a revolt I'm not sure I'll ever understand.
But I digress....if employees like WFH a lot better then they should have it.
Them: "I finished this over the weekend."
Me: "That's great, but you're to be clear you're not expected to do that. You should feel free to take weekends off to recharge!"
Them: "Yeah but what else am I going to do right now?"
If there hadn't been a pandemic, they would've been doing all of these other things and then more likely to cut back on work when the end of work hours roll around.
Honestly, IMO most of economics "research" is just a random assortment of bullshit viewed through a lens of confirmation bias. Results don't match your priors? Make adjustments to your model assumptions until it does. Disagree with a result? Point out at all the ways in which those assumptions are imperfect. Results match your priors? LGTM.
Should be studied more, but wouldn't you be surprised to know that the pandemic itself (stress, isolation, deferred medical care, etc.) caused an increase?
