Answer:
A neutral third party from outside the organization will hear the case via a nonbinding process.
Step-by-step explanation:
Assuming in an alternative dispute resolution program (ADR), the concerned employee and supervisor have finished the peer review stage and have not reached a settlement.
The most likely next stage in the ADR process would be to invite a neutral third party such as a mediator or negotiator from outside the organization, who will hear the case via a nonbinding process.
