Ask a lawyer to check if it is applicable in your jurisdiction. The number of appeals brought in labour law arbitration proceedings has increased in recent years. In a previous study, Colvin and Gough (2015) found: On average, between 2003 and 2013, 940 mandatory arbitration proceedings per year were submitted to the American Arbitration Association (AAA), the largest provider of work-balance services in the country.14 By 2016, the annual number of labor arbitrations submitted to the AA had increased to 2,879 (Estlund 2018). Other studies show that about 50 percent of mandatory labor arbitrations are handled by the AAA (Stone and Colvin 2015). This means that only 5,758 mandatory labour arbitration proceedings are still submitted each year throughout the country.
