This photo taken Monday, Oct. 28, 2013, shows William Shimer, part-time lecturer in management and organizational development at Northeastern University, standing for a portrait on the school's campus, in Boston. Thousands of part-time college professors are joining labor unions, a growing trend in higher education that's boosting the ranks of organized labor and giving a voice to teachers who complain about low pay and a lack of job security at some of the nation's top universities. Shimer said he never imagined being part of the union movement. But he has been rallying his colleagues to support an upcoming vote on whether to form a union. (AP Photo/Steven Senne) less
