Pros: Good benefits
I would work an eight hour shift on a rotating schedule, have eight hours off and then have to be back at work when my shift changed. I suggested that the rotating shift employees have their shift in a reverse order, where it would start on first (6a-2p), then move to second (2p-10p), etc. I was reprimanded for making a suggestion to upper management without the site managers "approval". I did this in accordance with the union handbook for security officers since I had also been trained as one, but it was still frowned upon.
I did, however, learn a lot about fire suppression systems in a large, automobile factory setting.
A typical day as an EMT, would be depending on which shift I was working that day. It was a very large plant (on over 3000 acres), so I had to know every inch of the inside and outside of the plant. Most shifts did consist of completing walk throughs of different buildings to look for fire, injured personnel, etc., checking on different components of the fire system and knowing what to do if they were to malfunction, responding to fires and injured personnel, doing multiple perimeter checks of specific areas to make sure things were secure.
The hardest part was honestly learning all the buildings and the fastest way to get to certain areas from the outside. This was a fully build-out plant, so cars went from stamping out the metal for the outside to assembly, then paint, then building engine from molten metals and assembly of the powertrain to go in the vehicles.
The most enjoyable part was when actually getting to perform my EMT duties, and help save lives, or prevent further injury.
