Whiskery, you will have to explain how you manage to work when YOU want. If I remember, I was only working WHEN AAI NEEDED ME. You are able to say no when you don't want to work (but you shouldn't say it too often because then you don't get called anymore) but you can't decide when you will work, so basically you take the crap they assign you to do and shut up. Some people might like it, as well as beeing away from home for up to 3 month at the time. I made my choice : NEVER AGAIN
