A Dean Health System manager removed a nurse from a minor surgical procedure last week in order to lay her off, a spokesman for the Madison, WI, company confirmed. The abrupt removal, which spokesman Paul Pitas said posed no danger to the patient, came after the Dean Health announced that it planned to "immediately" lay off 90 employees. Pitas, director of corporate communications, labeled the action "clearly . . . an error in judgment on the part of the manager conducting the layoff."
