The Market Basket board of directors and suspended CEO Arthur T. Demoulas will take their dispute to a mediator in September as the latest leadership struggle for the grocery store chain continues.

A spokesperson for suspended Market Basket CEO Arthur T. Demoulas accused the company’s board of attempting to silence associates demanding his return. The post Market Basket feud heading to mediation as Demoulas accuses board of silencing his allies appeared first on Boston.

Arthur T. Demoulas has been on paid leave since May, when its board of directors hired a law firm to investigate their claims that he had been preparing a work stoppage among employees.
