"When the people lead, the leaders will follow" are the oft-quoted words attributed to Gandhi. This week, massive grassroots organizing helped defeat the nomination of Andrew Puzder, a multimillionaire fast-food CEO, as Donald Trump's secretary of labour. He was widely accused of running companies rife with wage theft and sexual harassment. His personal life was marred by accusations of hiring an undocumented immigrant, tax evasion and domestic violence. The push for his defeat was led by some of the poorest and most vulnerable people in our society, and serves as a lesson in the importance and power of movements.
