WBUR, January 5, 2012 Boston - The National Labor Relations Board has filed a formal complaint against Steward Health Care for firing a nurse involved in organizing a union. A spokesman for the Massachusetts Nursing (sic) Association, David Schildmeier, says Steward was trying to scare off other unions by punishing the nurse. “They have actually gone after her ability to practice her profession as a way to punish her simply for wanting a union in her facility and for doing nothing wrong,” he said. “That is just unconscionable behavior and it’s beyond the pale.” Steward Health Care says in a statement that the nurse was fired for medical errors, and that her union-organizing activities played no role in her dismissal. Schildmeier says the company is putting financial interests ahead of employees.
