“ A certification by a state board under a different or conflicting theory of representation may therefore be as readily disruptive of the practice under the federal act as if the orders of the two boards made a head-on collision. These are the very real potentials of conflict which lead us to allow supremacy [10] to the federal scheme even though it has not yet been applied in any formal way to this particular employer. The problem of employee representation is a sensitive and delicate one in industrial relations. ”
