The answer is mediator; arbitrator

A mediator is a neutral third party who facilitates negotiations between two parties to help them reach a voluntary agreement. An arbitrator, on the other hand, is a neutral third party whose decision is binding on both parties. This option correctly describes the roles of a mediator and an arbitrator in the context of negotiations.

An arbitrator is indeed a neutral third party whose decision is binding, but an advocator is not typically involved in facilitating negotiations or making binding decisions. This option does not accurately describe the roles needed in the scenario.

While a mediator is correctly identified as a facilitator, an advocator is not a role that would make binding decisions in negotiations. This option does not fit the scenario described.

A shop steward is a union representative who helps represent workers' interests, but they are not typically neutral facilitators or decision-makers in negotiations. This option does not accurately describe the roles needed in the scenario.
