The lockout of union workers at Century Aluminum is over. United Steel Workers Local 9423 members voted by 68% in favor of a new contract and will return to work on Monday. It’s a five year-deal with a 2.5% raise the first year and 2.75% raise every year for the remaining years. Century will still contribute to employee pensions at the same rate and Craft employees will receive an additional $1.50 base wage increase.
