In the shop we worked 7-4 with some overtime. We also had a shop in 3 hrs away that we went to periodically with the service truck for a day or two each month and maintained 6 to 8 trucks down there. we did a lot of suspension and brake work, ABS, transmissions, clutches and some engine work. we did not do engine in-frames but we did almost everything else. we worked on Hydraulics and high pressure water pumps.
I worked directly under a shop foreman who organized the work to be done and prioritized. it was his job to get us the parts we needed to do the work.
My co-workers were respectful and easy to get along with.
