After a year of contract negotiations and 10 days of a strike, tensions boiled over between Proviso teachers and the west suburban school administration this week, with the union demanding the ouster of the superintendent after a confrontation at a board meeting.
Video of the Tuesday encounter, shared on social media and then by the school district, shows Superintendent James L. Henderson and school board member Claudia Medina in a heated argument over issues raised by the strike.
