WASHINGTON (Nov. 13)—U.S. congressmen serving on the House Taiwan Caucus have called on Continental Carbon Co.'s parent firm to help end an ongoing lockout at the U.S. company's Ponca City, Okla., carbon black plant. Rep. Sherrod Brown, D-Ohio, and Rep. Brad Sherman, D-Calif., sent a letter dated Oct. 22 to Leslie Koo, chairman of China Synthetic Rubber Co., Continental Carbon's Taiwanese parent. The letter urged the firm to "take immediate action to end the lockout and return workers to their rightful jobs." Continental Carbon locked out 86 members of Local 5-857 of the Nashville, Tenn.-based Paper, Allied-Industrial, Chemical & Energy Workers International Union in May 2001.
