The employer would like to show his appreciation for her past years of service and so he tells her that if she would like to retire he will contimnue paying her 50% of her current salary for the next ten years. A few years later the employer sells his business to a young sharp entrepreneur. He hires a sharp accountant and orders him to "cut ALL unnecessary expenses. The accountant finds these checks going to this former employee and the sharp entrepreneur stops paying her IMMEDIATELY. The old lady sues the company. Does she have a case?
