Pros
Caterpillar Global Mining (former Bucyrus Int'l) Mining Industry and company are stable Pay / Benefits are average to above average. Work life balance is favorable. Interesting Products, huge machines, lots of company history in South Milwaukee. Milwaukee and surrounding area is a pretty nice place to live; Milwaukee suburbs and SE Wisconsin in general are diverse and have alot to offer.
Cons
Organization can be an Old boys club with your opportunities limited by favorable or unfavorable status with certain management - favoritism typical of old school companies is hard to lose. Communication (top down) within the company can be poor, with some management bordering on unprofessional, yet some are really pretty good. Most of the company are still of a very conservative mindset. Other parts are driven by innovation - which results in some dysfunction. Dysfunction also due to recent history of acquisitions - Bucyrus acquires DBT and Terex, CAT acquires Bucyrus...has been messy.
