It’s one thing for the GOP to spend years working to take defined pension benefits away from workers still on the job, but at least those who have already retired should be safe. Only that's not the case. Some 400,000 retirees who worked in the trucking, parcel delivery and grocery supply industries face drastic pension cuts on July 1 as a result of a little-noticed measure attached to a huge end-of-year spending bill passed in December 2014. The provision in question goes after those whose retirement is funded through the Central States Pension Fund.
