Thе National Labor Relations Board seeks enforcement of its orders,
1. The contract with the Carpenters Union.
Respondent manufactures and installs overhead doors. In March 1965 and thereafter, its employees were represented by Sheet Metal Workers Local 108, with which it had a collective bargaining agreement. The agreement expired on July 1, 1965, but respondent continued to pay the union scale, including an increase effective July 1. In August, respondent expanded into overhead door installations in industrial buildings. Informed that this work was within the jurisdiction of the Carpenters Union, respondent approaсhed that union and on November 16 signed a contact with it to cover such work. The four installation employees affectеd were told by respondent to withdraw from Local 108 and to join the Carpenters if they wanted continued employment with respоndent. Two of the four joined the Carpenters, being reimbursed by respondent for their expenses in switching membership. Thereafter, rеspondent persisted in refusing to deal with Local 108 as representative of those of its employees who installed doors in industrial buildings, treating them as represented by the Carpenters and paying the Carpenters’ scale.
This was a direct violation of § 158 (a) (1) and (2). An employer has no more right to shove his employees into a bona fide outside union that does not represent them than it has to shove them into a company union. Insofar as the *1282 Board’s order rests on this violation, it will be enforced.
2. The contract with Local 108.
On August 31, 1965, Local 108 submitted copies of a new contract, effective July 1, for respondent’s signature. It was accompanied by a letter indicating that three copies of the agreement were to be signed by the respondent and one copy “retained for your personal use and convenienсe until such time as the officially signed contract by all parties involved is returned to you.” In November, shortly after respondent signеd a contract with the Carpenters, representatives of both Local 108 and the Carpenters met with respondent. At that meeting Local 108 claimed jurisdiction over the installation of service station doors, while agreeing that the Carpenters hаd jurisdiction over factory doors. On December 9 respondent’s lawyer wrote to Local 108, stating that respondent would sign an аgreement so long as it was understood that the installation of overhead doors would be assigned to the proper crаft — the Carpenters. Respondent signed the contract on January 11, 1966, and forwarded three copies to the union for signing. The uniоn did not sign the contract, and at a meeting with respondent on January 17 refused to accept respondent’s propоsal that Sheet Metal Workers continue to install doors on service stations and that Carpenters perform industrial installatiоns. The union also rejected respondent’s suggestion that the issue be submitted to the grievance procedure specifiеd in the contract. On January 18, the union stated that, under the circumstances, a contract between Local 108 and respondent would not be signed by the union. The union informed respondent on January 20 that it would strike unless the two installers who withdrew from Local 108 to jоin the Carpenters rejoined Local 108. Respondent again offered to submit the dispute to the grievance procedure under the contract if the union would sign it. This offer was rejected by the union and a strike began on January 24.
The foregoing facts аre not disputed. The trial examiner found that respondent signed the contract on the understanding that it not apply to the overhead door installers whose function fell within the jurisdiction of the Carpenters. The Board rejected this finding. It relied entirely on the fact that respondent’s letter of January 11, which accompanied the signed contract sent to Local 108, did not contаin such a condition. This, said the Board, was an acceptance of Local 108’s offer, and a contract camе into being on the terms of the written offer.
Whether the Board’s decision be considered a finding of fact or a conclusion of law, it is not “supported by substantial evidence on the record considered as a whole” (29 U.S.C. § 160(e)). Each party knew the other’s position: respondent was insisting that the contract should not cover the employees whose work fell within the jurisdiction of thе Carpenters; Local 108 was insisting that it cover them. Local 108 was not misled by its receipt of the contract without the acсompanying condition. The best evidence of this is what it did. Instead of signing and returning the contract and thereafter treating it as binding, Loсal 108 did not sign. Rather, it continued to argue and when the argument was unsuccessful, it refused to sign and called a strike.
We do not here repudiate the general rule of contract law upon which the Board relied, that an unconditional written acceptance of a written offer creates a binding contract. We find it inapplicable because here Local 108 knеw that the acceptance, while unconditional in form, was conditional in fact, and acted accordingly. N. L. R. B. v. Strong, 1969,
Insofar as the Board’s order rests upon its finding that there was a contract *1283 between respondent and Local 108, we decline to enforce it.
Judgment will be settled under Rule 19, F.R.App.P.
