Well, notanan2, I think some things are inherently more contact and complicated than your workplace. Some jobs require two pairs of hands. I wish my son-in-law worked for a company that was more responsible but I feel without compulsion some companies will not behave very responsibly to their employees.
You may ridicule my fears but I’ve seen it on the ground already I’m afraid, prior to lockdown.
So many businesses need two workers in close proximity at some point. Manufacturing of some items, lifting certain things, mechanics sometimes, house removals, people who travel to jobs in a works van with others, people in small spaces/workshops which require several people to function at all - these are very complex work situations and not at all easy to manage.
I’m not hostile to going back to work. I have a business, my mother had two, my father also added a business for 30+ years. I know what good employers look like. Unfortunately I also know what not-so-good ones do.
