why do bosses live in a fantasy land where people only get sick one day a year?

even jobs that have paid sick leave act like you’re only allowed to get sick for the amount of sick days you have, as if you control it like when you take a vacation. few things disgust me more than seeing bosses / managers guilt and threaten people into coming into work while sick. maybe the health department needs to start cracking down on it more, and not just in food service either. it seems like enforced legislation is the only way to get employers to treat people like human beings
