None that I can think of, except paychecks are received on time. Unless it's your final paycheck. Who knows when you will get that...
Cons
They do not care about their employees. Bonuses are offered, then changed, then taken away completely. The owners lie about everything from pay to bonuses to benefits to company culture to hours. There is no company culture. It is every man for himself.
The pay is pretty good. Coworkers are nice and motivated to get the job done. There is bonus pay available for the best drivers. The owners were always very respectful and personable people.
Cons
Some days that package load was outrageous. If you take too long to deliver packages they call you and tell you to hurry up as if you can go any faster. If you have to work after sundown it is a lot harder to see the houses/apartments to deliver the packages.
