Final answer:
The fourth step of the grievance procedure is where union grievance committee members and management's labor relations representative discuss the supervisor's first-step grievance answer, prior to arbitration.
Step-by-step explanation:
In the context of a unionized workplace, the grievance procedure typically involves several steps for resolving disputes between employees (represented by their union) and management. The step in the grievance procedure where union grievance committee members and management's labor relations representative are brought in to discuss the supervisor's first-step grievance answer is not during the arbitration step; rather, it is a precursor to any potential arbitration.
In standard grievance procedures, there are usually multiple steps before arbitration, which is often considered a last resort after other attempts to settle a grievance have failed. These steps usually involve escalation of the grievance through higher levels of union and management representatives before reaching arbitration. So, the correct answer would be 'the fourth step' if the procedure defined by the specific collective bargaining agreement indicates that this is the step when both parties are to meet.
