I have 2 weeks vacation, 2 floating holidays to take when I want, and 5 sick days. Of course, I'm never sick, so those don't count. Also, we have semi overtime... meaning, if you work 30 or more hours of OT in a month, you get a Friday off. However, you can't stack the days (once you've earned one, the next doesn't start accumulating until you use your current day), and you can only use one per 6 weeks...so if I earn one 4 weeks after a took one, I have to wait 2 more weeks to take it.
My team is small, only 3 people, so taking time off is hard. More than 3 days in a row sticks your coworkers with entire projects. Last year, I took both floating and 7 holidays off... and it was a lot. I have 13 days + 2 floating this year, and I've used both floating and 1 day so far.
I try to maximize my days... I end up with a friday off every 8 weeks or so, so that adds about 6 days to my year. However, since they aren't all together, they don't have the same effect as a solid vacation. I took Thurs, Fri, and Monday off last week, and that was considered a large vacation at my place.
