starting a new job!!!!!!

Hi,

I start work as a library assistant on Saturday and I am so nervous! I don't know what to expect and I like to plan my days and obviously, I cannot do that because I don't know what they will want me to do. I am going to have to talk to people for 7 hours!

basically, I want to know what to expect... what usually happens on the first day of a job?
