Established in 1982, the Western Conference of Teamsters Supplemental Benefit Plan currently provides an annual benefit to 18,722 retirees. The Supplemental Plan provides an additional annual benefit for retirees already receiving pensions from the Western Conference of Teamsters Pension Plan (the "Primary Plan"). It does not replace or affect the normal monthly pension from the Primary Plan. The Supplemental Plan is provided at no charge to retirees; the participating employers contribute (usually 40¢/hour) for active employees in order to provide this benefit for current retirees.
