Pros
Steady paycheck, plenty of opportunities to work on interesting projects, working conditions are generally OK, interaction with plant locations around the world; working here still looks good on a resume.
Cons
Professional progression is slow (averaging 12-15 years between mid-career promotions for good performers), and professional training/development is rarely supported if it involves overseas travel. Internal accounting prevents collaboration between groups. Purchasing anything takes several weeks to place the order and often requires follow-up with people located in India. Internet is frequently very slow at the main R&D site (5 minutes to download a 1 Mb journal article). Many of the facilities are in poor condition. Employee morale was low even before the latest lay-off (the largest in 30 years) or the announced plan to merge with Dow and then split into 3 companies.
