Fair point for some jobs, but not ours. Since a decent amount of our work involved being in the lab and/or pilot plant, our employees had to be fairly local, such that even during the worst of the pandemic we had to have about 50-70% of our employees still coming in to work (with some restrictions), as one can't do that kind of work without actually being on site. However, the "local" thing has never been an issue, since Merck recruited regionally/nationally and had our pick of the best candidates, who would relocate (being the premier chem eng'g process development group in Pharma had some benefits).
I'm sure there are jobs where WFH could have benefits outweighing being on site, but most of ours weren't in that category. My son, though, loves having a remote job with only having to go into the NYC office every couple of weeks to touch base with the rest of the employees (small, 25-30 person startup). I would probably feel similarly if 95% of my work was on a computer, as his is, and the alternative was a shitty commute to NYC every day from NJ.
