If you're sick and not feeling well, the best thing to do is stay at home and get rest (among many other things like get plenty of fluids). But, in the hustle and bustle of today's business world, taking even a single day off can lead to feelings of guilt and regret. Why this is I don't know.

But more bad things can be lurking behind that attitude. As in, what if you go to work and give everybody the flu or cold that you have? As an employer, this would not be a positive situation. In fact, staying home when sick is mandatory in some companies.

The loss of productivity from one person is enough, but if that person is the cause of even more lost productivity due to making more people sick, what would be the outcome? It would would way more than paying a single employee sick leave for a week, that is for sure.
