The Princeton Review reviews

TPR classifies all of its teachers and tutors as part time, regardless of longevity at the company or actual hours worked, to avoid paying benefits and fulfilling obligations owed to full-time employees. I worked there for over 3 years, sometimes as much as 60 hours/week, but was not offered health insurance or even a company email address. (Part time employees at TPR can pay out of pocket to join some kind of minimal coverage plan, but it doesn't meet legal standards to be considered insured). As a "part-timer," you receive no PTO and aren't protected by many employment laws, including the Family and Emergency Medical Leave Act. I had to take a couple of weeks off to recover from surgery, and when I returned, I was effectively demoted. None of my managers acknowledged it, but I was offered less work at a lower rate than I had been in the past, and after a couple of months of trying to get by on such, I left the company. Bottom line, don't sign a long term non-compete agreement with a company that will toy with your income.

Sometimes management can have knee-jerk reactions and will shoot first before asking questions. Thankfully, this doesn't happen often. The biggest problem you'll have, really, as an instructor with The Princeton Review, is back-stabbing students and parents, who despite singing your praises while tutoring or teaching, and despite significant score increases, will feel you didn't do a good job. (Two examples -- I had a GRE student whose score increased 160 points but still gave me a terrible review, and an ACT student whose father was not satisfied with a 5-point score increase despite the guarantee of 3 points, and the fact that such a huge score increase is extremely rare.)
