We’re listening back to a conversation with one of Milwaukee’s celebrated labor leaders who fought for migrant workers’ rights: Jesus Salas. Salas co-founded Obreros Unidos (Workers United), which led a historic march in 1966, demanding lawmakers address violations of the state’s minimum wage laws and housing codes.

For Salas, defending migrant laborers and their rights is a personal call to action. He was a migrant worker alongside his family starting when he was 7 years old.
