Wearing an armband with the word "fast" on it, Sofi Shank admits that her decision to put her body on the line for her beliefs isn't sitting well with her parents. "They're really concerned about my health," said Shank, 19, a University of Minnesota freshman. "My dad hasn't been getting sleep; he's been calling me all the time." On Monday, Shank was one of 11 university students who began a hunger strike in support of striking clerical, health care and technical workers. The students -- who are also being joined by one professor and a university civil service employee -- will drink water and juice, but they vow not to eat again until the university settles the contract dispute with the AFSCME-represented workers.
