Pros
The engineers I interact with on a daily basis are extraordinary people. The are tops in US for chemical production, and #2 in the world. One of the companies that still have a pension (after 3yrs vested). Great advanced materials R&D units. If you play the games -- you'll go far.
Cons
BPSC was a terrible place to work, but I got "out". Low salary compared to industry standard. Too bureaucratic. Too cumbersome. Too many politics. Too many union doofusses at the plant. Nothing exciting about living in Midland, MI ... snotty town with nothing special except the pius populace. HR at Dow has effectively taken the human out of Human Resources ... they run the company, not the managers or directors. Your career is limited by your manager and your job classification (Admin, Tech/Tech, FS/FL). If you're Admin ... good luck getting promoted and even if you're over qualified. Time to move on for me ... resigning at most ample opportunity. I've worked in chemical industry for over 20yrs and this is the worst one I've had the misfortune to work for ... I regret taking the job.
