As a Brazilian this whole discussion is absurd. Here, we all have sick days. Not unpayed, full compensated sick days. Everyone. It's law. You have a medical order saying you can't work? Stay at home bro. If it's for more than 15 days, the federal government will pick up the slack and pay tour wages in form of a “sick insurance”. For as long as it takes. And, in the meantime, you're protected from firing, and in the months following your return. It's madness in the US. It really makes on think, its very easy to have a big economy and produce hundreds billionaires when you're making it all at the backs of the labour class.
