I have worked for an insurance brokerage for 21 yrs at which time in Sept 2015 the brokerage was sold to another firm as the owner retired. At the time of our purchase the new owners reassured us that nothing would change. I have an employment contract that has been in effect since Feb 22, 1999. On a separate occasion I was reassured again that they would honor the terms of my contract. Now they want to tie me into a new contract which is totally not acceptable. What are my options? Do I have to sign this contract? What can they do if I do not agree to the terms of the new contract?
