An arbitrator overturned the demotion and suspension of the former firefighters' union president in relation to actions at a New Year's Day 2017 fire that killed three people, displaced 49 tenants and destroyed a building. The decision by the American Arbitration Association said there was no evidence that Chad Cunningham ignored orders or violated rules and ordered he immediately be returned to his former rank as lieutenant and be awarded back pay. The decision ruled the city singled out Cunningham for discipline because he was the head of the firefighters' union and in that role publicly criticized Fire Chief John A. Pond and Mayor Alex B. Morse for the temporary shut down of Engine 2, saying it restricted firefighters' abilities to fight the blaze at 106 North East Street. "The evidence does not support the city's claim that the investigation was part of a 'routine' post-incident analysis," the decision said.
