To the folks who are thinking that city workers should pay for supplemental Medicare like private sector retirees, I would just point out that the offer of retiree health benefits to city employees was a major reason why many chose to enter city work, as opposed to working in the private sector where compensation tends to be higher. To retroactively change these benefits for retirees who already completed their service to the city, and who planned their retirement based on having these retiree health benefits available, is fundamentally unfair and may be considered against the law when this change is ultimately challenged in court. It would be like your private employer deciding to claw back their 6% contributions to your 401(k) after you have already retired.
