Employees at the supermarket chain Market Basket in Massachusetts are slamming their new co-CEOs' pleas for them to drop their walkout, as protests for the return of their beloved ousted boss gain steam. The employees are angry over the firing and replacement of former CEO Arthur T. Demoulas by his cousin after decades of bitter feuding. The spat has outraged a large number of people, including company workers and shoppers, who have organized walkouts and protests that have left many Market Basket stores empty.
