Questions about soon to be nursing assistant position

[cmm4ever]

So I go for my huge physical next week for the hospital nursing assistant position I was offered last Wednesday. The recruiter was telling me things to bring/expect at the place. I was wondering if everyone else has to go through as extensive physical as this. I guess I will have a regular physical, plus ppd skin test, drug test, have to bend, lift, stretch, something about the treadmill and a bunch of other things that I have to bring and do. This will not be done at the hospital. Also anyone working at a hospital do you get shift differential for weekends and how much is it? I will be working 7-3 part-time and rotating weekends and holidays. Also this is a union job, so how long do you think I will have to wait to bid for full time etc? Of course now there are 2 different full time day positions posted for associates..which I guess Im not oficially yet. How often are your raises and how much. Thanks for your help!
