As mentioned in the article – retiree health care will be hit first. There’s legal precedent – even when it *is* contractually indicated (as in union contracts).
I’m just finishing up an excellent book called “Retirement Heist” by Ellen Shultz (WSJ). She goes into great detail how healthcare benefits were much easier to cut and then eliminate, compared to pensions.
Her book does not cover public employee plans. But it’s pretty eye opening anyway.
