TEWKSBURY, Mass. — More than 2,000 employees and supporters rallied at the Market Basket supermarket chain headquarters Friday demanding reinstatement of the company’s former chief executive.

Organizers said they hope to shut down the family-owned chain’s warehouse and deliveries to its 71 stores in Massachusetts, New Hampshire and Maine to put pressure on the board that fired Arthur T. Demoulas last month. They said more rallies are planned and urged workers to stand together.

“We can shut this company down, and that is the only way we’re going to gain the attention of the board of directors,” said grocery supervisor Tom Trainor. “There is one way to make a greedy person listen – in his wallet,” he said. Many warehouse workers took sick days or vacation time Friday. Other employees attended the rally in their work attire.
