Reliant believes that the demands of ministry are such that it is extremely difficult, in most cases, for a full-time employee to perform a second job without serious impairment of work performance. Therefore, Reliant expressly reserves the right to restrict outside employment whenever such employment adversely affects job performance. In the event that an employee's job performance is adversely affected in either quality or quantity by secondary employment, the employee will be required to discontinue one of the jobs. Secondary employment is not an appropriate justification or excuse for tiredness, tardiness, absenteeism, poor performance, or an inability to work appropriate overtime hours.
