My husband works for the UPS twilight shift and has been at the hub for a great deal. Though he manages to keep two jobs (an 8-5, and a 5-9 at UPS) he is doing a great deal at UPS to keep busy and focus on loading boxes on the trucks.
One thing that gets me though is the fact that some of the workers do a lot less and get the same pay as my husband, sometimes even more because of the higher "status" they have achieved (a.k.a seniority). Its frustrating sometimes to hear that my husband had to work harder since a person or people on his belt have/had been slacking off.
Also, it seems as though drug testing seems slack, since my husband has worked on the twilight and midnight shift and he has continually seen many men get "high" before both shifts. I think that the lack of drug testing has caused many of the workers to become slack and thus there is a dire need to have a stronger stance on the use of drugs before work.
