b.Investigation procedure. For the purpose of this paragraph, "director" means the director or the director's designee. Upon receipt of the written complaint, the director shall acknowledge the complaint in writing. If the complaint raises issues which could result in disciplinary action, the director will investigate the complaint. The investigation may include an informal, confidential hearing by the director for the purpose of ascertaining more clearly all relevant aspects of the complaint. No subpoenas or sworn testimony will be taken. The employee, the complainant, and other parties and department staff as invited by the director, may participate in the hearing. Counsel for the employee and the complainant may participate in the hearing. Informal cross-examination of all parties will be allowed. The hearing shall be tape-recorded. At the conclusion of the investigation, the director will prepare a written response to the complainant; except that the response shall not violate the employee's rights to confidentiality under Iowa Code section 22.7, applicable collective bargaining agreements, or any other applicable statutes or administrative rules.
The written response of the director shall be the final agency action regarding any written complaints received under this subrule. Nothing in this procedure shall be construed to prevent a withdrawal of the complaint based on an informal settlement between the department and the complainant.
