Chiplote fires many over immigration status

"Chipotle Mexican Grill said it fired 450 Minnesota workers over their immigration status last year, more than a third of its workforce in the state. But the Denver-based restaurant chain said in a filing with the Securities and Exchange Commission last week that it complied with the law when reviewing employee work authorization documents and that some of their employees may be unauthorized workers “without our knowledge.” It also said it didn’t know if it will face penalties in connection with the matter."
