Paul was employed by David as the day shift manager of David's fast-food restaurant pursuant to a written and signed one-year employment contract. After six months on the job, David orally promised to pay Paul a bonus of $3,000 for his excellent work. David indicated that the bonus would be included in his next paycheck. Paul was not paid the bonus. Nonetheless, Paul continued to do the work. The following month, David orally told Paul that he would raise Paul's weekly salary by $250 if David agreed to work the night shift one night per week.
