Police pensions are protected by police unions. Abolishing police pensions would almost certainly require kneecapping their labor rights. Sorry, I realize now that I left explanation of this logic step out of my first comment. What I am essentially asking is, how would you undermine police unions without also undermining all unions, and thereby all labor?
This has definitely been attempted, in fact I would reckon that the majority of police contract negotiations begin on the topic of pensions as it is one of or possibly the largest cost associated with running a police agency. But as no union worth it’s salt would ever budge on the one thing that is most important to it’s members - Teachers, longshoremen, delivery people, factory workers, none of them have ever given up pensions because it would be wildly against their primary interest - It hasn’t happened yet. What would you do differently to convince police unions to abandon their retirement plan (Or replace it with something that can be deducted from or penalized conditionally)?
