first class 1 job offer

1st post guys so be nice
been driving class 2 for nearly 3 years then decided I wanted to get away from it and move onto the bigger motors.
working at a foodservice firm making £30k a year but the work is hard going, 15hour shifts, handballs, stairs and your never going fast enough for the office, and the routes never get completed unless its the guys who are clearly tipping on breaks etc.
anyway been offered a start with a haulage firm near Edinburgh, they don’t have a great reputation on this so wont name them but the works better, amazon-glenrothes to amazon-Peterborough then back, same journey twice, 4 on 4 off tramping. moneys about the same but I’m thinking purely for experience and the easier workload it wont be too bad a move.
anyone agree or disagree with this?
