Not sure about that NW.
When i transferred to my current office, i went from FT contract at old office to 30hr contract at new .
Wasnt happy about that, but it was my decision to transfer, so had to accept it ( got back to 40 hr contract a few months down the line )
When i was on 30hrs, most weeks i was on FT walks, so was booking 2 "Up hours" every day, plus OT if i went over time.
However the first 10 hrs OT is only paid at standard rate, which is a con. I questioned the union rep about it at the time, saying that if i had exceeded my contracted hrs (30) then surely any hours on top should be at OT rates, reply was that basically the union had cocked it up.
Gone a bit offtopic from initial post, sorry.
