Pros
This is a thriving and forward thinking company not afraid to take the steps to survive in a changing business environment. While a lot of other retailers cling to their catalogs, Grainger embraced online shopping even to the point of cannibalizing their own books. It is a strategy that works.
Cons
Such a big company gets very small with "little chieftens" allowed to run their little empires. Leadership doesn't have the time or care to reign in this layer of insulated bureaucrats and, unfortunately, in some cases abusive bosses. While it is clear that people on the same level as these offenders recognize the patterns of favoritism and abuse as they are repeated over and over by the worst, very sick offenders, they admit they fear for their own jobs and while privately sympathizing with victims, don't do anything.
