I know I get some sort of sick days for my current job, but I don't know how many, and if they are paid or unpaid. The employee manual doesn't say (other than that I do get sick and vacation days), and I've asked in a roundabout way, only to find out the secretary (who handles all these things) doesn't really know either.
Unlike some of the posters in this thread, I stay home when I'm sick. Period. I may lose out on the $40 I would have made that day, but I would rather just eat ramen for the next two weeks than have to go into work when I'm not feeling well. My job involves contact with a lot of children, who can be difficult even at the best of times, and I know that even if I'm not throwing up, a throbbing migrane will be 10x worse and will probably make me snap at the kids. (Not to mention passing it on to them!)
Luckily, my employer is very understanding of how life works - sometimes you get sick, sometimes you're running late, and sometimes you're not able to put 100% into your job. I think it's because this is such a small town - if someone stays home one day, well, everything can be put off until tomorrow. Nobody is essential to the running of the town.
