Some employers (way too many) regard coming to work despite being sick as not only praiseworthy but pretty much expected. In those workplaces, people who come to work sick are regarded as harder workers, more dedicated, etc.

Then there are the employers that give employees one bucket of paid time off that is used for everything (illness, vacation, anything else that comes up), which incentivizes people to work through illness in order to have more pto available for vacation.

And let us not forget the legions of poorly paid workers who get NO paid time off of any kind and come to work sick because they can't afford to lose a day's pay.

The way this country treats its workers (in many ways, not just this) is a travesty.
