It does seem excessive. I get paid for Canadian Stat days when I am closed, and also 10 personal days a year. So that's for sick and vacation. I give a month's notice for vacation dates and tend to hang on to a couple of personal days in case I get sick at the end of the year. I do have in my contracts that I can take more than 10 days with appropriate notice but I've never done it and the extra time would be unpaid.
