Final answer:
The question pertains to the percentage of collective bargaining agreements that include mediation in the grievance process. Exact percentages can vary and need up-to-date research data for accuracy. Historically, the trend has been towards including mediation, hinting at a possible higher percentage, but without current data, a precise answer cannot be provided.
Step-by-step explanation:
The question seeks to determine what percentage of collective bargaining agreements include mediation as a component of the grievance procedure. It's important to note that specifics can vary by region and change over time. However, without access to the most current and specific research data, it's not possible to provide an exact percentage.
Surveys and studies conducted by labor relations organizations or academic research typically provide this information. If we're looking at historical data, the use of mediation in collective bargaining agreements has been encouraged as a way to resolve disputes without escalating to arbitration or litigation, which might imply a higher percentage. Nonetheless, without updated data, any answer would be speculative and not necessarily accurate.
