Final answer:
Kerri Anne is acting as an arbitrator who has the power to impose a decision on the conflicting parties of management and union if they cannot agree on wage increases.
Step-by-step explanation:
Kerri Anne, who has the authority to impose a decision on both parties if they cannot come to an agreement themselves, is acting as a arbitrator. The role of an arbitrator is particularly important in situations where management and unions are at an impasse regarding issues like wage increases. This function differs from that of a facilitator or mediator, who would typically assist the parties in finding a resolution without the power to impose a decision, or an ombudsperson, who generally investigates and resolves complaints in an organization.
Having an in-house dispute resolution process or involving a neutral third party like an arbitrator can be crucial to addressing unresolved conflicts. These measures help in preventing stress, loss of morale, potential staff departures, or lost productivity due to ongoing disputes. In this context, Kerri Anne's role is vital in ensuring that the dispute reaches a conclusion, allowing all parties involved to feel supported and maintaining the overall health of the workplace environment.
