Joe,
You should at least get some time off for the Holiday. Don't let them screw you out of your vacation time like I did. We had a Needs of the service clause and it was supposed to be so in case of an emergency they could cancel vacations but the company twisted it around to stop me from taking any as they claimed I was the only one qualified on all the different computers and satellite systems, I wound up losing 15 weeks of vacation. I should have did what a guy in L.A. did and just vanish for a while. They received a call from him in Europe and he told them he would be back in 10 weeks and they could either have his pay ready or he would go back to work.
