Hi there.
First off just a couple off questions. Where have you applied for the job and what did you do previously?
Weekend working and working hours are dependent on what shift pattern you are on. On my shift I get about 3 weekends off every two months but I know some who get 1 weekend off a month and some that get 2 off a month.
Different bases get different wages and benifits. As a Servisair Dispatcher at Gatwick I get about £7.50/h and £212 shift pay a month, thats about 16.5 grand a year.
The hours worked in a week are the average taken for the whole month. I do 37.5 hours a week but because i'm doing a 6 on 3 off shift I could do more than the average or less than the average at any one week. It also could due to overtime as in this job overtime is easily available. I think they're just confusing you.
