The union representing SBC`s 100-thousand employees says it`s disappointed with the company`s latest contract offer. The Communications Workers of America expressed frustration yesterday with the pace of negotiations with the nation`s Number Two local-phone company. The CWA also expressed "extreme disappointment" with SBC`s latest proposal. San Antonio-based SBC says talks were continuing and hadn`t hit an impasse. The union could still call a strike with 24 hours` notice. The Dallas Morning News reports CWA president Morton Bahr is scheduled to talk later today with local union leaders from across SBC`s 13-state service area, which includes Arkansas. SBC`s old contract with the CWA expired on April Third. Health care costs and job security issues have been sticking points for three months in the talks. The CWA last struck what was then Southwestern Bell in 1983.
