Pros

No pros because I worked for Guardian Industries Corp a subsidiary of Koch and after 37 years nothing good to say.

Cons

I was released from employment without warning after 37 years of dedication because I demanded my annual performance evaluation after 5 years without one.

Great employee base, People tend to work here for a long time. They provide a lot of emphasis and training on their principles, which can be a good and bad thing, They do stick to them which I respect.
