The IAM National Pension Fund
has provided valuable retirement benefits for members of the International Association of Machinists and Aerospace Workers and their families since 1960.
The IAM National Pension Fund provides participants with a defined-benefit pension plan for their retirement.
While defined-benefit plans were prominent in the past, unfortunately only 12.2 percent of private-sector workers have previously stated they had access to a defined-benefit plan like the IAM National Pension Fund. These benefits fortify a crucial part of the three-legged stool of American retirement consisting of Social Security, employee pensions, and personal savings.
