Selectmen will meet Tuesday with representatives from the University of Massachusetts Boston’s Collins Center for Public Management to begin discussions about whether to hire the center to recruit candidates for town manager. The board bought out the remaining year of Kevin Paicos’s contract last month after a mutual agreement not to renew it. Town Clerk Bob Cutler, who has been acting as town manager, told officials Tuesday that he’s not a candidate for the permanent job but will continue to fill in until a replacement is found. Several selectmen, including chairman Mark Sullivan, said they were disappointed with Cutler’s decision not to seek the job. All thanked Cutler for his service, including Selectwoman Virginia Copolla, who said the town had needed someone like him “to calm the waters” after Paicos’s exit. Separately, Paicos has been hired as interim town administrator in Northfield, working 20 hours a week until the town fills the position permanently.
