Legally, UPS has four Trustees on the New England fund representing fifty percent of the voting authority. All multi-employer funds are trusteed by half-Employer and half-Union representatives. These Trustees must obey ERISA, the IRS, the Department of Labor and all other Laws which carefully define what the Trustees can and can't do. As Fiduciaries, Employer Trustees' obligation is to the Fund, not to their specific employer. They can't make biased decisions favoring the company they work for. They are like a Little League umpire who happens to have a son playing in the game. He must obey the laws. He can't favor his kid.
With each new Contract UPS negotiates and signs, it strongly recommends a "Yes" vote containing this clause . . .
ARTICLE 69 - PENSION FUND
Section 1
(b) The Employer agrees to and has executed a copy of the New England Teamsters and Trucking Industry Pension Fund Agreement and Declaration of Trust dated April 11, 1958 and accepts such Agreement and Declaration of Trust, as amended, and ratifies the selection of the Employer Trustees now or hereafter serving as such, and all action heretofore or hereafter taken by them within the scope of their authority under such Agreement and Declaration of Trust.
You'll be happy to know that with the troubles YRC has been having, their Trustee had resigned and been replaced by a guy from Bimbo Bakeries!!! Really.
UPSers don't get all the benefits their contributions should have earned them because of several major market declines, because of the insurance feature of the plan, under which the survivors slightly subsidize the unfortunate ones, and because of about two dozen UPS policies that are largely incompatible with successfully earning a generous pension under plan rules.
When other company workers become orphaned in various ways, their benefit entitlement is almost always reduced or limited proportionately under plan rules to reflect a level that they contributed to and hence actually bought and paid for.
Note that UPS orphaned all Central States UPSers who retired prior to 2008.
