Members of the Minnesota Nurses Association will be in Mankato next week to support the nurses at Mayo Clinic Health System. A press release from the Minnesota Nurses Association says Mayo nurses have been in negotiations with Mayo on a new three-year contract since September, but management has refused to negotiate with nurse members in the room. The MNA has filed an Unfair Labor Practice charge with the National Labor Relations Board against Mayo Clinic Health System. Mayo has responded with their own charge against the MNA for allowing nurse members to participate in the process. The picket is scheduled for December fifth outside of the Mayo Mankato hospital.
