I was given a 30 day, non contract renewal letter after no indication of performance concerns or professional concerns. I have worked back to back contracts for 2 years with no indication that the job or position was changing for the upcoming school year. What are my rights as an Ontario employee.

It sounds like you may have been subject to consecutive fixed-term contracts, and/or were characterized as a contractor by your employer. In either case, you may still be entitled to a severance package greater than the period of notice you have been given. We encourage you to contact our firm and schedule a consultation with one of our employment lawyers who can review your contract, and assist you in obtaining your lawful termination entitlements.
