The company petitions for review, contending that the Board’s analysis under its own precedent is flawed and unsupported by substantial evidence. The Board ruled the company violated Sections 8(a)(3) and (1) of the Act by terminating the welders because of their union membership. Absent the usual statutory obligation of the parties to maintain the status quo upon expiration of their collective bargaining agreement, until impasse or a new agreement is reached, the Board had to determine whether the Hawaiian Dredging Construction Company’s discharge of its welders, after their Section 8(f) agreement had expired, was motivated by an intent to discriminate in violation of the employees’ statutory rights, or reflected the company’s long-standing business practice to rely on union hiring halls under Section 8(f) agreements for craft employees. § 158(f), allows employers in the construction industry to enter into pre-hire agreements with unions without a showing that a majority of their employees support the union.
