As an important aside, I'm sure everyone has noticed that grocery store clerks aren't allowed to wear masks in practice. I'm sure everyone has noticed quite a few other jobs where this is so. It seems endangering the lives of certain kinds of workers is nearly universal. Not to excuse them but I imagine Amazon has a lot of company in this[1]. I am very glad at least Amazon employeesare doing something about it.
