If your company didn't make the top 50 but it is reasonably large, you can probably find it here:

Scroll down to the Alphabetical Listings "@Roa - Acad
Acad - Adva" etc. if your company isn't on the main list. I found that the reviews have many insightful comments, with separate sections on "Pros", "Cons", and "My Advice To Senior Management".
These lists always bother me because the one characteristic the companies listed always seem to share is: "It's a big corporation with thousands of employees". Precisely the one characteristic that immediately takes it off my list of "great place to work."
