Glassdoor is a little like Yelp. It can sometimes become a place where people unsatisfied with their jobs go to vent. But itโ€™s also become a place people rely on when theyโ€™re job-searching, to find out if maybe the hiring manager (or worse: recruiter) was embellishing that great benefits package or if the salary wasnโ€™t just what they thought it would be.

So we looked through Glassdoor to find the skinny on some of Philadelphiaโ€™s most well-known companies (and others that employ the most people here). The database holds 8 million company and job reviews; for starters, hereโ€™s a look at each company, and the percentage of people who said they would recommend the job to a friend.

The most popular? UPenn. The least? The School District.
