I posed this quesion on the ups contract facts website recently and received a reply.
"If in the future it is found that healthcare funding as negotiated in the National Master is inadequate, will our benefits be reduced?
The benefits are locked in for the entire five-year contract. Under TeamCare, your benefits are less likely to be reduced because Teamster trustees are on the fund, unlike with the company plan. As you witnessed, the company has made drastic changes to management’s plan recently and was going to do the same for its workers. That’s why TeamCare was chosen, to protect benefits and keep costs low."
Do "locked in" and "less likely to be reduced" mean the same? Not to me...
