Pros
Good place for people in protected classes - women, minorities, and people over 50. 3 for 1 company match on charitable giving. Beautiful office environment in Lake Forest. Most departments seem to work reasonable hours, but that is not always the case. Profit sharing is decent.
Cons
Heavily political - I've worked for several Fortune 500 companies, but Grainger is the worst in this respect. I keep wondering how some of these managers and directors have gotten to their positions. Senior leadership does seem more competent. Compensation can get really out of whack. Some of the worst employees can be paid significantly higher than some of the best employees. HR makes it very difficult to fix these issues. Also, there seems to be no rhyme or reason for which positions are eligible for restricted stock units.
