Employees by Region
In 2004, we experienced a couple significant industrial relations issues that had a major effect on our earnings. By years end, the issues had been resolved.
ABI At our ABI smelter in Quebec, Canada, a strike started in July after extended negotiations. Within the first 10 days of the strike, two out of three potlines were completely shut down. However, ABI had 100 salaried employees running the production of this one potline. While this was not our desirable state of production, there was community and media support for Alcoa. There have been some very positive outcomes from this, including addressing outstanding issues regarding pensions and staffing models. In addition, one of our U.S. locations had additional capacity restarted to help supply some of our customer commitments.
