how many workers are losing by working remotelyI think the big losers are the service workers that provided services for all of those office employees: coffee shop workers, restaurants, drycleaners, caterers that provided employee lunches, cleaning people, etc.
A Starbucks, a drycleaner and 2 or 3 restaurants that were in my former office building have shut down permanently. My company stopped stocking snacks and catering lunches 3 days a week, and presumably they or the building have cut back on cleaning as well as general building maintenance staff.
Some of those jobs will come back when (if) we return to in-office work, but since it will probably be part time in-office work, not all of those jobs will be back.
Food trucks seem to be doing pretty well - when employees dispersed, they did too. I don't go into the city much since I don't go to the office, but now I visit the same food trucks in my own town and they seem to be pretty busy.
