The Peer 84 rule applies to part-time UPS employees participating in the Western Conference of Teamsters Pension Trust (WCTP). Under this rule, you may qualify to retire when your age plus years of service equal 84. For example, someone who is 60 years old with 24 years of part-time service would qualify. Like full-time employees, your pension amount depends on the total number of hours worked and contributions made on your behalf—not just your age or service.
