Lorraine,
There are several dozen pension plans that cover UPSers in various areas of the country. Management plans are different than Union plans, and sometimes, part-time is different than full-time. To give you advice we need to know:
Was your husband a Teamster, or Management, or a pilot, or a member of the Machinists Union, or some combination?
Were all the years worked in New Jersey, or elsewhere?
What Local or Locals was he in?
Do you have any Annual Benefit Statements and Summary Plan Descriptions (SPDs) that you should have been receiving in the mail over the years?
What is the formal name of the Pension Plan(s) on any of those documents.
Now-a-days, most plans have websites with all the information you need. We can point you in the right direction, but we need more info.
Generally, if you fall short of the 25-year milestone, you still qualify for a pension based on the 24-plus years, but it is at a lesser rate. A wife is normally entitled to her husband's pension. There may also be a death benefit available.
You should also check into extending your Health & Welfare Plan coverage through the COBRA option.
