Stephen Muka owned U.S. Robotics. He hired his brother, Chris, to work for the company. His contract promised Chris $1,000,000 worth of Robotics stock at the end of the year “provided you work reasonably hard and perform satisfactorily…” Chris worked the full year, but toward the end of the year Stephen died. His estate refused to give Chris the stock, claiming their agreement was a personal satisfaction contract and only Stephen could decide whether Chris had earned the stock. What should be the test of satisfaction in this case? Explain.
