Pros
A great many people are able to work from home. And they do provide good bennies, particularly the health plan. (The health plan got a little less good while I was there, but it was still quite good. That erosion may be a harbinger of things to come.)
Cons
Lots of managers who have risen to their Level of Incompetency. (Read the book The Peter Principle.) Good chance that'll be your manager. True story: During my time there a close relative passed away. I searched out Pearson's bereavement policy to clarify how much time off I was allowed, and I discovered that when it's a close relative Pearson will also, upon request, either send flowers or make a contribution in memory of the person who passed away. Sounds nice, right? But wait. After I came back I asked about getting that contribution made. My department told me to take it up with HR (even though the policy says it's done through the department). HR sent me back to my department, in accordance with the policy. You'd think somebody would manage to step up and see that it got taken care of! But no.... Also, be aware that Pearson has a crappy reputation, and they're shedding people and selling off business units to try to turn things around. But based on what I saw, I don't think it will work. Pearson will circle the drain for years to come till they finally disappear.
