In fact, taxpayers (public employers) are prevented from negotiating with public unions in a meaningful way, so contracts forced upon them are invalid.
The biggest thing to understand here is that the pensions ARE NOT BEING CUT - the Cost of living allowance is being redone. That is what fueled the rulings, and the rulings are correct.
Just as with a private pension, the only thing the retiree is garaunteed is that they will recieve a pension. Yearly increases for public pensions are just gravy.
I am a military retiree, and while I like the idea of annual COLA’s the fact is the only thing I was promised was a % of my final pay. Any raises are completely at the mercy of the rules at that point in time, and I am fine with that.
When there are only so many jelly beans in the jar, the sooner we face up to that reality the better.
