Sem (emergency maintenance) is an absolute disaster as well as all the other driver support systems they would leave you go for hours at best at times days you could talk to one person they tell you one thing then talk to someone else and get a completely different answer the pay is low for the job but not too bad the additional hourly pay is pretty nice although they only want you to use a fraction of it then the time off is also pretty rough and they're treatment to drivers is pretty rough too I mean they don't even give you towels at the showers they offer in they're facilities they're constantly firing or having people leave almost every third person who was also a driver I ran into with them either had plans to leave weather it was retiring or quitting they send new people to rough places they'll keep ya out for longer then they tell you they will just all the time they're training is very fast paced it's very sink or swim just toss ya in the deep end and see how you sort yourself
