Several workers at University of Iowa Hospitals and Clinics have filed complaints alleging their supervisor hid a baby monitor to listen in on their conversations. Workers union representative John Stellmach, president of AFSCME Local 12, said two secretaries and three clerks in the Department of Urology discovered a baby monitor hidden in their office Monday morning. Stellmach said the workers thought the monitor, which they said was plugged in and turned on, had been hidden with the knowledge of their direct supervisor, a HR representative and an administrative assistant. Stellmach said the workers, whom he declined to identify, think the monitor was put in place to determine if they were talking too much on the job. "Instead of just being rational and coming and talking to them, apparently the manager had talked with the HR person and they decided to put a baby monitor so they could hear what was going on," Stellmach said. "But what they failed to realize is that's very illegal."
