Final answer:
Grievance mediation is a true method of dispute resolution involving an outside neutral to help resolve grievances without arbitration. It is a step before considering arbitration when internal mechanisms fail.
Step-by-step explanation:
Grievance mediation is indeed a process where an outside neutral assists the parties in resolving grievances without resorting to arbitration. This statement is true. When an informal approach has not been successful and no internal mechanism exists to address the dispute, a neutral third-party mediator can be brought in to facilitate a resolution. Mediation serves as an accessible and impartial dispute resolution option. Should mediation not resolve the issue, arbitration may be considered as a more formal step, where an arbitrator would make a binding decision.
