DYER, C. J.: The National Labor Relations Board here seeks enforcement of its order1 finding respondent Certain-Teed Products Corp. in violation of section 8 (a)(5) and (1) of the National Labor Relations Act2 for its refusal to bargain in good faith with its certified union. The Board's finding is based on the company's conduct during a limited period of a long series of negotiations between the company and the union. The union was certified on July 2, 1964, and negotiations began in September, 1964. At that time the parties agreed that discussion of economic issues would be postponed until all other issues were resolved. Although the services of a mediator were utilized no agreement was reached, and in January, 1965 the mediator suggested that the company and the union were in deadlock and that further meetings not be held until a change in position occurred. On June 1, 1965, the union wrote the company requesting that negotiations be resumed. A meeting was arranged for June 25.
