Employees also can make complaints directly to the ERU. Regardless of whether a complaint is filed with an employee’s department or with the ERU, the ERU determines who will conduct the investigation. It’s possible that complaints could be sent back to the victim’s department for investigation. In these instances, the employee charged with investigating the case may report up to or have a long-standing relationship with the victim or the individual accused of misconduct, making an unbiased investigation difficult if not impossible.
