The second study is about employee satisfaction, which I didn’t argue as well. The third study may be a thing, but it doesn’t outright compare those who work in an office to those who work full remote.
And as I’ve said earlier, it is fine if you want to make arguments for WFH outside of productivity. However, none of the studies you provided tries to directly measure the two. Thank you for providing some studies, though. You were the only one who tried to argue this via academic studies.
