I really hate working my birthday, but have sucked it up and done it the last few years. I could book the day off, but it will mean a day less to spend with DC in the school holidays, and an extra day's childcare to pay for. Oh, and due to the stupid leap year I'll miss a weekend birthday day so feel that I've been robbed.
I'm also working all of Christmas/New Year other than the weekend and the bank holidays.
