Quit my "job" over this

robroy:
Thought that was what agency was …hiring yourself out on an hourly rate.
It was an unforseen circumstance which often happens in transport.
If I was getting paid 12 hours for sitting on my arse for the same as 12 hours graft, it wouldn’t bother me tbh.

Have to say I’m in full agreement. As an agency driver I expect to be the one to get the arse end of the deal. If I had enough hours and it was a driver who was running out and it was the difference between him getting home or not I’d have not hesitated, in fact I would have actually volunteered and I have done exactly that a few months ago, giving my load which was ready to another driver who had something important to get back for who had been waiting hours for his and was going to be waiting another hour or two after I’d be long gone.

Lorry driving is going to throw you things like this and worse. If you’re not prepared to accept it then you need to go find another field to work in.
