There are two legal tools that could be triggered if SU and the State cannot reach an agreement.
Mediation is where both sides select a mutually-agreeable mediator, though this can take several weeks. A mediation session is then scheduled, which can mean a delay of several months. If there is still not an agreement after this months long process then the next step is arbitration.
Arbitration also requires both sides to mutually agree on an arbitrator, then an arbitration session is scheduled. Like mediation, this usually results in a delay of weeks to months to get to the arbitration session. The decision of the arbitrator is binding only on the union.
Class I employees in the SU bargaining unit must submit to binding arbitration and cannot participate in a lawful strike. They include, police, fire, correctional, and some hospital employees.
