875—9.17 (88) Withdrawal of complaint. Enforcement of the provisions of Iowa Code section 88.9(3) is not only a matter of protecting rights of individual employees, but also of public interest. Attempts by an employee to withdraw a previously filed complaint will not necessarily result in termination of the commissioner’s investigation. The commissioner’s jurisdiction cannot be foreclosed as a matter of law by unilateral action of the employee. However, a voluntary and uncoerced request from a complainant to withdraw the complaint will be given careful consideration and substantial weight as a matter of policy and sound enforcement procedure.
