BOXFORD, Mass. — A veteran Boxford police officer wants his time working as a lifeguard for a state agency decades ago counted toward his pension.In a letter to a state appeals board, John Iannazzo said working as a lifeguard for the state in the 1970s and '80s qualifies as a "temporary" job that should be credited toward his retirement.Adding Iannazzo's lifeguard service, which totals nearly two years, would increase his retirement benefit by 4.6 percent, according to the Essex Regional Retirement System.
