Sort of ... I work 16 hours a week (friday and sat) and i'm paid like if i was working 20 or more ... (and i really work 14 hours ...) so i can't really complain BUT when a work is cancelled there is nothing i can do ... I'm independant but i'd like a real permanent job to make plans, with this one i can't really.
And i have to look for my contracts all the week and month to be sure i'm booked as much as i can. But i change of shops and things i must sell very often, so collegues, chiefs etc .. are never the same, it's a good thing. Each time i want to change i go back to this situation, it's easier and better i guess ... And after a few years i'm asked for more interesting things now and can negociate the price a bit easier now

(and can be more exigent too, about the shops i prefer to work etc etc ... in which department, for one product in particular ... )
If you'd win the euro million, would you stop working ?
