An interfaith coalition of religious leaders, joined by labor and civil rights groups, is organizing a day of protest and witness on next Monday’s 31st anniversary of the assassination of Rev. Martin Luther King, Jr. The Interfaith Worker Justice committee is leading the effort and organized a press call this afternoon. Specifically, the groups are calling attention to the need to defend workers’ rights in the face of political attacks unleashed on organized labor in recent months. Dr. King was shot in Memphis, where he had gone to stand with striking garbage workers.
