Can you have arbitration without a labor union?

Yes. Arbitration resolves disputes between parties, regardless of the setting. In the workplace, most arbitration takes place as a way to resolve disputes that occur in the application or interpretation of collective bargaining agreements between employers and the unions that represent workers. That process may take place pursuant to agreement of the parties or, generally in the public sector, pursuant to statute. However, employers may offer arbitration as a way to resolve workplace disputes with employees even in the absence of a union by adopting arbitration language in policy, employee handbooks, or contract. Individual contracts of employment may also be written to provide for resolution of disputes through arbitration. Occasionally, the courts refer parties to arbitration.
