A 64-year-old former Cohasset municipal employee has filed a complaint with the state alleging that he was discriminated against by town officials because of his age, the latest in a series of personnel disputes within Town Hall.

Mark D. Brennan filed a complaint against the town and Acting Town Manager Michael Milanoski with the Massachusetts Commission Against Discrimination, alleging that because of his age he was stripped of his duties as director of operations for Cohasset and treated poorly, and that his job eventually went to a much younger man.
