Surgery DATE...?

I started a new job at a hospital, Been there a couple of weeks, and I love it. I can see myself doing it for a long time even retiring from it. I also been working on my surgery requirements since June. Today at work I received a call from the surgeon's office. They want to schedule my appointment for November 26th. Two days before Thanksgiving. I am very happy. However, I either get the surgery and loose my job or keep the surgery and don't do the surgery.  I am a temporary employee. They need me for the holidays. Chance are that of course If they need to downsize or anything , I am the first one to go. However all the other temps in the department had really good luck and have now even permanent positions. My dilema is, I can either just work until my surgery, leave and when I am all well try to apply again or forget about the surgery for a while. But then again is my health right. Me not having serious medical problems and not being severely obese is a priority right.. I am very sad, but I guess I will work until I cant work no more, and continue with my surgery arrangements. There are plenty of other jobs out there, and only one of me.  So I have to take care of my body, before I can take care of anyone else. So yes, November 26th it is. =)  By the way, so far I lost 16 pounds!
