Market Basket’s Board of Directors voted unanimously Tuesday night to fire longtime President and CEO Arthur T. Demoulas after mediation between the two was unsuccessful.

In a lawsuit explaining their decision, the board noted that it had “repeatedly tried to work with Demoulas for years to gain his cooperation.”

“Demoulas would have none of it,” the lawsuit stated.

This comes more than a decade after an unrelated family feud nearly destroyed the beloved Tewksbury-based grocery store chain. Market Basket lost millions of dollars in revenue when Demoulas was ousted from ownership by his cousin back in 2014.
