Chicago Business reports that La Casa del Pueblo, a small independent grocery store in Pilsen, has been busted by the National Labor and Relations Board for threatening to fire workers, have them deported, or close the store if employees continued with their efforts to organize and join Local 881 of the United Food and Commercial Workers Union. Store owners are accused of firing employees, cutting hours, and forcing employees to take unpaid vacations. The Chicago Journal reports that the grocer also worked with a Franklin Park union in attempts to unionize the store with them. It's illegal for an owner to take part in the formation of a union.
