The plan covered 3,000 workers in Washington, Oregon, Idaho, Montana, and Alaska, and provided workers at retirement with a maximum pension of $75 a month. Employers paid in 10 cents an hour for each worker to build annuity reserves for the first two years. The first pensions were payable in 1957. Eligibility was based on years of service.
At the time of the contract signing, other programs were being set up in all Western states. The plans were administered from the Seattle offices of the Teamsters Union, and were intended to supplement federal social security.
