Working conditions - Forklift Driver DB Schenker Employee Review

I've worked for schenker for 2 years now. You get treated like dirt while casual and even worse on probation. Finally going permanent but starting to think do I really want a futur where the manager treats you like poo. Got told if I had any issues speak with our manager I did today and could not have been nicer and got a verbal warning. This is really unfair. Cant say anything good about working there now.
