You can get the hours
First of all, they will promise you anything when you start your interview. Belive nine of it if it's not on paper.
Second: If you're lucky, you'll get your uniform in time (read if you got a site that is important to them and the client is a high importance one).
And third: The management and those guys in comms have no interaction between each ither. So they have different files on you (talk about efficiency and simplicity) and if you told your manager you're not available on per example Mondays, the comms will send you a roster with Mondays because the management didn't pass on the info on you, so you have to call comms to make them aware of your availability.
To make it even more complicated, a branch manager has an assistant, and miraculously he has an assistant too. :D
Anyway, if you hmHAVE to work with them, the way to deal with this company is to be very persistent and bore them to death with your requests (even though they were supposed to be given to you without even asking).
PS: Sunday allowance means +0,5€ per hour, and night allowance means you have to sleep with someone or bore them to death.
Loads of hours if you want to have nonlife / Be on call floater.
No life, they'll call you even on holidays, let laone on your days off.
