Pros

Fantastic place to work. Especially operations. Smart, process oriented individuals. Good pay and benefits.

Cons

Corporate can be a bit disconnected from the plant operations. But this is expected at any distributed manufacturing organization.

Good Pay, Bad Management

Pros

Really good pay, especially if you are an overtime hog. You'll learn alot there. Especially with Rockwell PLC programming and instrumentation.

Cons

It gets boring sometimes because a lot of our work is contracted out. Just line calls and work orders. Stay as far away from the HR and management offices as possible. They are not your friend. Pretend like they dont exist and just do your job and keep your head down.
