Nurses at Centerpoint Medical Center in Independence, MO, have submitted a petition to decertify from Nurses United Local 5126, an affiliate of the American Federation of Teachers' healthcare division. In 2007, Nurses at Centerpoint Medical Center voted to select Nursing United Local 5126 as their exclusive agent. Poor communications with management, on-call and vacation issues, nurse-patient ratios, and pay were among reasons cited. But during the ensuing year, Nurses United was not able to negotiate a new contract with Centerpoint.
