Emma Employee works as a salesperson. Her company International Widgets implements a sales incentive program- If any salesperson sells 100 units in July, they will receive a $12,000.00 bonus. International states that the program is discretionary and that International may change it at any time. Emma is the only salesperson to sell 100 units in July. After she finishes her sales, Emma is told by International that due to the fact that overall company sales were down, they will invoke their discretionary right and will only pay her a $6,000 bonus. If you are on either Learning Team A or C, set out International's argument as to why it is legally justified to make this change.
