Pros
Decent opportunities for new positions and career changes so long as you don't mind situations where they have already selected a candidate rather than interviewing for one. Their shareholders love them! Buy PPG stock as it has been profitable and paid uninterrupted dividends for 130 years. I guess when they pinch the pennies out of their employees it affords them the ability to be profitable.
Cons
PPG suffers from many of the same tragedies as many of the big global corporations. Poor middle management who ride the success of their employees, a lot of overpaid dinosaurs who are protected by the good ole boy network, and senior management who get high returns on short term decisions with long term negative consequences. Salaries and bonuses are a joke to anyone who is not management. My best bonus in 5 years of working as a senior analyst for Corporate IT was 3% despite stellar reviews in my annual P&LP. The average was 1.5 %. I guess they figure that we get enough perks with our partner discounts ($5 off a gallon of Manor Hall paint and Aquapel windshield repellant at Christmas)! Raises are crap - typically less than cost of living increase. People work to the bone for nothing. A friend of mine lost his daughter to cancer and they pressured him to come back to work or else losing his job.
