To simplify administration and respond to employee concerns, UC is changing the eligibility rules for retiree health benefits.
This means that those employees who previously had been moved to the new 2013 eligibility rules because they were not vested in UCRP on June 30, 2013 or because their age plus years of UCRP service was less than 50 at that time will no longer be subject to the eligibility rules that went into effect on July 1, 2013.
