to include a charge that the union had threatened the initial complainant .because he had filed the unfair labor practice charge. In April, 1967, the same discrimination charges were filed against PMA. The charges have also been amended to incorporate certain other casuals as discriminatees.
Uncontradicted testimony of the complainant before the Hearing Examiner revealed that the president of the Union had stated that consideration was given to Local 6 men because they were “union men * and will go out ahead of any casual people.” There was further unrefuted testimony that the union president had made certain intimations to the complainant that economic and physical reprisals would be taken against him because he had gone to the National Labor Relations Board. Finally, the record before the Hearing Examiner revealed that the preference given Local 6 men was not based on any special skills or ability that they possessed; they were indiscriminately assigned to work that could have been performed by joint hall casuals.
Based on these facts, the Board adopted the Hearing Examiner’s findings that the Union had violated sections 8(b) (2) and (1) (A) of the National Labor Relations Act and that the PMA had violated sections 8(a) (1) and (3) of said Act by jointly operating an exclusive job referral system in a discriminatory manner which encouraged membership in Local 6. The Board also found the union guilty of violating section 8(b) (1) (A) of the Act by threatening and coercing the complainant because he exercised his rights under the Act.
In seeking review of these determinations of the Board, PMA makes three basic contentions.
First, PMA argues that it did not know of the discrimination involved, and, in the absence of such knowledge, cannot be found guilty of violating the Act.
The Board has advanced the contention that once an employer assigns a union as its exclusive hiring agent, it is jointly liable for any discriminatory acts which occur, and cites Morrison-Knudsen Co. v. N.L.R.B., 275 F.2d 914 (2d Cir. 1960), cert. denied, 366 U.S. 909, 81 S.Ct. 1082, 6 L.Ed.2d 234 (1961) and N.L.R.B. v. H. K. Ferguson Co., 337 F.2d 205 (5th Cir. 1964), cert denied, 380 U.S. 912, 85 S.Ct. 898, 13 L.Ed.2d 798 (1965) to support this view.
PMA argues that these cases do not purport to affix absolute liability on the employer unless he actually knows of the activity, and notes that this was the holding of N.L.R.B. v. Master Stevedores Assn. of Texas, 418 F.2d 140 (5th Cir. 1969).2
However, in Morrison-Knudsen, the court explicitly stated, “regardless of the extent of their (employer) knowledge * an employer may not avoid liability for violations of the Act by the hiring hall when he has turned over to it the task of supplying the men to be employed.” 275 F.2d at 917. (emphasis added).
In any case, we find that there was sufficient evidence of PMA’s knowledge. In the first place, the hiring hall here was a joint venture, supervised by a committee comprised of PMA and Union representatives. Thus, PMA, “by reasonable diligence should have known.” N.L.R.B. v. Houston Maritime Assn., 337 F.2d 333, 336 (5th Cir. 1964). In addition, we note charges were first filed against the Union in December, 1966, but not against PMA until April, 1967. Throughout that period the discriminatory system continued in effect. The charges against the Union should have put PMA on notice. See, e. g., N.L.R.B. v. Local 269, IBEW, 357 F.2d 51, 57 (3rd Cir. 1966).
PMA secondly suggests that Local 6 was the locus of the discrimination. Thus, the argument goes, the Local 6 practice of discriminating against its
