On the December 31st, 2014 edition of Your Call, we'll have a conversation about how people power can make big companies change their ways. Walgreens recently bowed to public pressure to remain in the US after considering moving overseas, and Oxfam successfully pushed General Mills to cut greenhouse gas emissions. What tactics work? How have the emergence of social media and the sheer size of multinationals changed what it takes to win? Join the conversation on Your Call, with Rose Aguilar, and you.
