Boston-based pizza chain The Upper Crust is under attack from without and within. The Globe shares further details about the lawsuit involving accusations that one of the company's co-owners misused $750,000 of Upper Crust dough for stuff like trips to the Cayman Islands, a down payment on a house and a private airplane. Meanwhile, The Upper Crust is still under federal investigation for exploitative labor practices. Though the offending owner has been placed on leave, he denies all accusations. Unsurprisingly, the company recently shuttered its third location in recent months, though nearly twenty remain open.
