As of 2007, the exempt employees (all non-union) paid a portion of their health insurance based upon their plan. It was $300/year for a single person; $480 for a 2-person family; and $660 for more than 2 covered on a family plan.
I believe that AFSCME Local 2058 also paid these amounts in 2007, though I don't know if their contractual amounts changed since that date.
When the city declared exigent circumstances, part of the changes were that the non-union, exempt employees starting paying the 10% employee portion of their PERS pickup that the city had been paying for them. In the past, the city has extended the pension pickups negotiated for union employees to the exempt employees.
I recall that Collins, in 2010, had presented an ordinance to again have the city pay that 10% after the mayor re-negotiated the union contracts and removed the exigent circumstances. I don't know if they actually voted on that agenda item.
