We have duly considered the issues presented on this petition for review of the order of the National Labor Relations Board; and,

After considering the record and the oral arguments and briefs of the attorneys, we are of opinion that the order of the labor board should be enforced, save in one respect: Namely, the respondent should not be required, as ordered by the board, to reimburse those of the respondent’s employees who were members of the union involved before going to the Nolin River project.

It is so ordered.
