When I was a feeder newbie, I worked straight nights in coverage. There was 1 bid job that was available that everyone passed on that was a day job, and I took it. It was a shifting job, started at 1:00pm. Broke for lunch around 5pm, made a CPU, then shifted till the midnight lineup was in, around 11pm. I was assigned a yard mule, then jumped into a tractor for the CPU. I think I worked that job 2 years. It was an armpit of a job, especially in the Texas heat, but since I just came out of PC, sweating was nothing new to me. I sure learned to back, build sets, and yard etiquette. I think rookies should be required to shift for a least a minimum time before they are let loose on the motoring public.
