Labor Notes: Union Official, College Lecturer Don Giljum Resigns After AFL-CIO Pressure, UM-KC Won't Rehire Next Semester by Dan Riehl 28 Apr 2011 post a comment Share This: The latest development in University of Missouri-St. Louis union/labor course fall-out via Labor Notes. Earlier Big Government reports here, here and here. The attorney for the Missouri AFL-CIO, Ron Gladney, called Giljum’s international union and asked officials there to pressure him to resign from his local and international positions, which they did. Giljum resigned, despite the fact that he had announced back in January he would be retiring May 1—just days away. According to Giljum, Gladney argued that the incident might cause Missouri Republicans to take up a right-to-work bill, which they have till [sic] now avoided. The University of Missouri-St. Louis told Giljum he will not be rehired next semester.
