It's amazing, though, how some companies will micro-manage your time. Considering my current employer, it's a damned good thing I wasn't working for them 8-9 years ago when I was in the hospital for two weeks after being run through the medical wringer for two months of tests prior to that.
Here, they do a running total of sick hours, and if you've got any more than 40 in a running 12-month period, to the supervisor you go. That may sound like a lot, but get a cold or a flu twice in a year, there you are.
