Compensation often impacts an employee’s motivation and job satisfaction, although it is not the only factor. According to an article written by Mae Lon Ding of Personnel Systems Associates, compensation systems positively impact a large percentage of workers' performances. Many employees feel motivated to help their companies succeed if the employer shares its profits with employees, such as with bonuses or profit-sharing plans. The greatest impact of money on productivity and performance is in jobs where performance is directly related to compensation. For example, the knowledge of receiving a bonus after achieving a certain sales quota will likely motivate a salesperson to increase productivity.
