Any such authorization may be withdrawn by the employee by giving at least sixty days' notice in writing of such withdrawal to the state, county or municipal officer, or the head of the state, county or municipal department, board or commission, by whom or which he is then employed and by filing a copy thereof with the treasurer of the association.
