Final answer:
The final phase of the grievance process is typically arbitration, which involves an independent arbitrator making a binding decision.
Step-by-step explanation:
The correct answer is option 'going to arbitration'. The last stage of the grievance process often involves having an independent arbitrator decide on the issue when internal negotiations and discussions have been unable to resolve the dispute. This stage is known as binding arbitration, where the decision made by the arbitrator is final and must be respected by both the union and the company. This process is preferred in situations where resolution cannot be achieved through the normal channels of union-management negotiation, mediation, or other dispute resolution processes set forth by the National Labor Relations Board.
Arbitration is the last stage of the grievance process in which an impartial third party, known as an arbitrator, makes a final decision to resolve the dispute between the company and the union. This decision is typically binding and cannot be appealed. The arbitrator listens to both parties' arguments and reviews all relevant evidence before making a decision.
