Report
Decent place to work but not great.
-The Bad
People in the front offices have a strange attitude towards the shop workers
People in the shop are pretty grouchy and will smile to your face but talk behind your back. If you do work through temping you have to work an absurd 640 hours then have to work an additional 90 days before benefits kick in. The standard level of quality is pretty low and "good enough" most of the time. The Equipment in the shop is pretty dated and poorly maintained.
Parts are scattered throughout the shop and "pn-hand" materials like bolts and nuts are constantly out
