The outsourced employees had been participants in Honeywell’s defined benefit plan, which provided early retirement benefits and retiree medical benefits. However, after the outsourcing, the employees became covered by FES’s two defined contribution plans. In two separate lawsuits filed in the US District Court for the Western District of Missouri, the plaintiffs claimed that they lost their right to future benefit accruals and their retiree medical benefits as a result of their outsourcing, and that Honeywell had terminated them in order to interfere with their pension rights in violation of ERISA Section 510. However, the district court granted summary judgment in favor of Honeywell, and on appeal, the Eighth Circuit affirmed that ruling.
