In June 1993, the Company adopted a policy to create a company-wide smoke-free operation.  A collective bargaining agreement adopted in 1993 did not change a provision that had been in place since 1978, allowing smoking in designated areas within the plant premises.  An arbitrator ruled that the new Company policy violated the collective bargaining agreement and ordered that the Company rescind the policy and follow the terms of the agreement.
