City worker pension funds board members learned last week that retiree healthcare plan costs will be going up hundreds of dollars a month in 2017 now that the city has completely phased out its annual retiree health plan subsidy. According to a presentation made by Comptroller Erin Keane to pension fund boards, individual retiree plans will go up almost $600 a month to $1,466. Family health care plans for retirees will go up almost $1,400 to $3,622 a month.
