There’s a ton jobs, including mine, that require people to be on-location.
Aircraft mechanics can’t exactly bring the plane home. Retail employees can’t sell stuff from home. Manufacturing and construction jobs (aside from maybe some planning and design?) can’t be done from home, etc.
I often wonder, when I’m sitting in traffic, how many of these other people have the ability to do their jobs from home, but can’t because their upper management is forcing them into the office.
