Despite threats by new management to fire any workers who fail to perform their duties, some 300 warehouse workers and 68 drivers have refused to make deliveries. So far, eight supervisors have been fired. Massachusetts Attorney General Martha Coakley, who is running for governor, and New Hampshire Gov. Maggie Hassan have publicly supported the employees.

The feud dates back to the 1970s, but the most recent round of infighting began last year when Arthur S. Demoulas gained control of the board of directors. Last month, the board fired Arthur T., sparking the current uprising.
Workers are fiercely loyal to Arthur T.
"You know the movie, 'It's a Wonderful Life.' He's George Bailey," said Tom Trainor, a district supervisor who worked for the company for 41 years before being fired last weekend over the protests. "He's just a tremendous human being that puts people above profits. He can walk through a store, and if he's met you once, he knows our name, he knows your wife, your husband, your kids, where they are going to school."
