The third day of the strike by University of Minnesota clerical workers passed with no sign of movement from either side to break the impasse. No talks have been scheduled since the negotiations broke off Monday evening. Since the strike began the two sides have disagreed about how many workers have taken to the picket lines. The university says nearly sixty percent of the 19-hundred workers covered by the clerical contract have shown up for work. Union leaders say the number is half that.
