Where employees of a public agency do not have a recognized or otherwise designated representative, the agreement or understanding concerning compensatory time off must be between the public agency and the individual employee and must be reached prior to the performance of work. This agreement or understanding with individual employees need not be in writing, but a record of its existence must be kept. (See
§ 553.50.) An employer need not adopt the same agreement or understanding with different employees and need not provide compensatory time to all employees. The agreement or understanding to provide compensatory time off in lieu of cash overtime compensation may take the form of an express condition of employment, provided (i) the employee knowingly and voluntarily agrees to it as a condition of employment and (ii) the employee is informed that the compensatory time received may be preserved, used or cashed out consistent with the provisions of
section 7(o) of the Act. An agreement or understanding may be evidenced by a notice to the employee that compensatory time off will be given in lieu of overtime pay. In such a case, an agreement or understanding would be presumed to exist for purposes of
section 7(o) with respect to any employee who fails to express to the employer an unwillingness to accept compensatory time off in lieu of overtime pay. However, the employee's decision to accept compensatory time off in lieu of cash overtime payments must be made freely and without coercion or pressure.
