I was terminated today without being written up or put on a performance plan. No valid reason was provided. I have been employed for 2 years and 8 months in HR. They want to give me 8 weeks of pay - is that enough or am I not entitled to more?

Unfortunately, an employer does not need a "valid" reason to terminate an employee's employment if they are terminating "without cause" - i.e. with the provision of severance pay. As long as the reason for your termination isn't discriminatory, then the company was legally entitled to terminate you, provided that your severance package is sufficient. 2 months of pay for 2 years of work sounds to be in the likely range of your entitlements, but it is never a bad idea to have it reviewed by an employment lawyer at the number below, to be sure.
