Boeing files unfair labor practice against union

WASHINGTON, D.C. — Boeing said late Thursday it had filed an unfair labor practice charge with the National Labor Relations Board (NLRB) against the union representing its striking US West Coast factory workers, accusing the leaders of not bargaining in good faith.

The charge is the latest sign of the growing acrimony and increasing frustration in the labor talks as the strike by about 33,000 union members enters its fifth week and piles financial pressure on the struggling planemaker.
