(3) There shall be a moratorium on employees' receipt under this division of credit for service with the state government or any of its political subdivisions during the period from July 1, 2003, through June 30, 2005. In calculating the number of years of total service under this division, no credit shall be included for service during the moratorium. The moratorium shall apply to the employees of the secretary of state, the auditor of state, the treasurer of state, and the attorney general, who are subject to this section unless the secretary of state, the auditor of state, the treasurer of state, or the attorney general decides to exempt the office's employees from the moratorium and so notifies the director of administrative services in writing on or before July 1, 2003. If an employee is exempt from the moratorium, receives credit for a period of service during the moratorium, and takes a position with another entity in the state government or any of its political subdivisions, either during or after the moratorium, and if that entity's employees are or were subject to the moratorium, the employee shall continue to retain the credit. However, if the moratorium is in effect upon the taking of the new position, the employee shall cease receiving additional credit as long as the employee is in the position, until the moratorium expires.
