As we mark the 7th year of the Marikana tragedy, we take a look at the question of how unions bargain with employers. How they reach the point of calling a strike or get into a confrontation as we saw in Marikana. The frustration faced by the worker and also what determines the amount they demand from an employer. Also the people who died on this day, have they changed the course of collective bargaining?

GUEST: Dr Denis George, who is an Expert in collective bargaining and social partnership
