Among the many important lessons that can be taken from the Minnesota resistance to ICE is the role that organized labor can play in struggles for social justice. Unions from the Minnesota Education Federation to the Service Employees International Union to the Amalgamated Transit Union helped organize some of the multitude of protest actions in the Twin Cities of Minneapolis and St. Paul. Not only did their participation help broaden the fight, but it is also proving to have strengthened the labor movement and individual unions. One example is outlined in this article by Minneapolis letter carrier Emmett Bongaarts, first published by Labor Notes. His branch of the National Association of Letter Carriers organized two protests during the ICE siege to demand that ICE stop using postal property to stage its raids; individual members of the local also participated in activities to help defend their immigrant neighbors. Organizing around immigration spurred a number of union members to start attending local meetings for the first time.
