“ The Board, however, was not forced to conclude that the subsequent activities of Independent erased the effects of the employer's earlier discrimination, any more than it was compelled to believe that the employer's later show of impartiality obliterated the consequences of its prior interference with the employees' freedom of choice. We cannot assume that the employees will be free from improper restraints and will have the complete freedom of choice which the Act contemplates where the effect of the unfair labor practice is not completely dissipated. ”
