   3. (3)The employee has exhausted grievance-arbitration procedures pursuant to § 708.14, and issues related to alleged retaliation for conduct protected under § 708.5 remain.
2. (b)Pursuing a remedy other than final and binding grievance-arbitration procedures does not prevent an employee from filing a complaint under this part.
3. (c)An employee is considered to have filed a complaint under State or other applicable law if he files a complaint, or other pleading, with respect to the same facts in a proceeding established or mandated by State or other applicable law, whether such a complaint is filed before, concurrently with, or after a complaint is filed under this part.
4. (d)If an employee files a complaint under State or other applicable law after filing a complaint under this part, the complaint under this regulation will be dismissed under § 708.18(c)(3).
