Maybe mine isn't as applicable to the Auto Industry, however, over the last 9 years I've held jobs in manufacturing businesses in:
The Boat/Marine sector
Defense (electrical distribution systems)
Oil and Gas related support/construction support
Aerospace <- UAW shop workers...............I'm amazed there are any Boeing parts still made in this country
Oil/Gas/Towing/Defence
As for UAW it's not just wages and benefits, stuff like X amount of floor space must be converted to break rooms so there is at least one seat in each section of each building for when everyone goes on break, and long lists of all other kinds of ridiculous garbage.
