I'm a CA employee. My original (Canadian) employer was acquired 18 months ago by a global firm based in MA.
I had negotiated a 3 month severance payment for any reason other than Cause with my original employer. I have email confirmation from the former CEO agreeing to the terms. I also have a document from HR with the terms, which I signed - but was never signed and executed on the employers due to distractions of the acquisition.
Other provisions of the agreement around salary and bonus were put in place. HR has told me though that the severance provision is not in effect due to the terms of the Employment Letter signed subsequently with the acquiring company.
Although it did not address any terms around severance, the Employment Letter stated that the terms and conditions set forth in the Employment Letter represented the "entire agreement" between the employer and me, superceding all prior negotiations.
The CEO of the old company was aware of the pending acquisition when he negotiated the terms with me.
Do I have any grounds to enforce this documented but un-executed agreement with my original employer and demand the agreed 3 months severance in the event that my employment is terminated? The company is currently providing around 2 weeks severance to terminated employees.
