Nurses from two Medical Centers make up our Union membership and are represented by Local 40. These members are RNs and LPNs from Mt. Clemens Regional Medical Center (MCRMC) and RNs from Crittenton Hospital Medical Center (CHMC). We are a Local of Office and Professional Employee's International Union (OPEIU), which represents more than 1400 nurses in the United States of America and Canada. Membership between the two Medical Centers equals approximately 900 nurses and is divided into "units" within the Union: MCRMC RN Unit, MCRMC LPN Unit and CHMC RN Unit.
