FORT WORTH, Texas (June 7)—The Fort Worth regional office of the National Labor Relations Board issued a complaint May 31 for two unfair labor practice charges against carbon black producer Continental Carbon Co. The charges are related to disputes with the Paper, Allied-Industrial, Chemical and Energy Workers International Union, which represents workers at Continental Carbon plants in Ponca City, Okla., and Sunray, Texas. In May 2001, the company locked out PACE Local 5-857 in Ponca City after the local's 85 members failed to ratify the firm's final economic proposal during contract negotiations. Both charges - one stemming from a PACE demonstration held three months ago at Continental Carbon's headquarters and one related to the firm's alleged failure to share environmental information with the union - originally were filed in March. A NLRB hearing is scheduled for October in Houston.
