formed Mr. Webb, the company manager, that the union represented a majority of the employees; he demanded recognition and bargaining and suggested a meeting on August 4th. Webb declined recognition and told the union representative to contact the company’s counsel. At an employee meeting on August 9th stewards were elected, and it was agreed that if any employee was discharged all would go out on strike.
On August 12th, Streater went to pick up the company truck in Oklahoma City, where it had been undergoing extensive repairs. Earlier, a repair list had been drawn up by Streater at Webb’s direction, including among other items repair of the truck’s inoperative air horn, a horn in addition to the truck’s regular horn. When Streater arrived at the shop in Oklahoma City the horn had not been fixed, and after he and the shop mechanic unsuccessfully attempted to fix it, Streater ordered that it be replaced with a new one. He returned to the company office where he left the bill for all the repairs. On August 13th, Streater was discharged, being told that it was for dissatisfaction with his work and for the unauthorized purchase of the horn. He offered to pay for the horn but was refused.
When the union stewards learned of Streater’s discharge they called on Webb for an explanation. Webb replied that the discharge had nothing to do with the union. The following day all but one of the plant employees walked out in protest. Webb refused to reinstate Streater, and the strike continued. On August 26th, the employees tendered an unconditional offer to return to work, but by then they all had been replaced.
On September 29, 1969, the Board’s Regional Director in Fort Worth issued a complaint charging that the company’s behavior constituted multiple unfair labor practices. A hearing thereon was scheduled for late October, but in the meantime the Board brought an action against Acker Industries in the United States District Court seeking temporary injunctive relief under section 10(j) of the Act, 29 U.S.C. § 160 (j), pending final Board action. The relief sought was of essentially the same design as that prayed for in the section 10(b) complaint; specifically, the District Court was asked (1) to order Acker to reinstate Mr. Streater, (2) to order Acker to reinstate the strikers who had been permanently replaced, and (3) to order Acker to recognize and bargain with the union. The United States District Court held a full hearing and later it filed a memorandum opinion in which it was stated that Acker was not guilty of unfair labor practices, and findings to that effect were made. Acker immediately applied to the trial examiner for leave to amend its answer to plead the section 10(j) findings as binding by collateral estoppel or to reopen the record in the section 10(b) hearing just concluded to receive a copy of the memorandum opinion. The trial examiner refused. The Board concluded that the company violated section 8(a) (1) of the Act by threatening its employees with plant closure. It was also found that Streater’s discharge and the company’s refusal to reinstate the protesting strikers constituted violations of section 8(a) (3), and that the company violated section 8(a) (5) in failing to bargain with the union. The Board’s order requires reinstatement of Streater and his co-workers, allows for back pay, and provides for recognition and bargaining.
The respondent argues that the United States District Court’s findings, conclusions, and judgment in the section 10(j) injunction action are binding on the Board under the doctrine of estoppel by judgment, citing Gaitan v. United States, 295 F.2d 277 (10th Cir.), and similar cases. It urges that management made no threat of plant closure, that the Board’s finding that Streater was discharged because of his union activity is not supported by the record, and that the strikers were not entitled to reinstatement because the strike was not an unfair labor strike. It is further argued that it was inappropriate for the
