Does the doctrine of exhaustion of remedies apply where a party has filed a complaint against the NLRB but has not yet held hearing on the complaint?

6 Of course, in the present case no "adverse administrative determination" has yet occurred because the district court has enjoined all separation proceedings against the plaintiffs. But even where an adverse determination has not yet been made, a party may still be required to exhaust its administrative remedies. See Myers v. Bethlehem Shipbuilding Corp., 303 U.S. 41, 50-51, 58 S.Ct. 459, 463-64, 82 L.Ed. 638 (1938) (doctrine of exhaustion of remedies applied where NLRB had filed complaint against company but had not yet held hearing on complaint).
