“…Second, the primary focus of the literature has been on interest-based ADR practices, such as 'assisted bargaining', 'facilitation ' and 'interest-based bargaining' (IBB), where agreed third parties provide support to the collective bargaining activities of employers and unions (Acas, 2005;Branney, 2019;Euwema et al, 2019;Klingel, 2003;Kochan et al, 2016;McAndrew, 2014). Much less attention has been focused on the adjudication or arbitration of otherwise unresolved disputes or on arrangements combining adjudication with interest-based practices like mediation (Klingel, 2003;McAndrew, 2014;Roche et al, 2014;Steadman, 2003;Thompson, 2010). Third, while, as earlier discussed, ADR practices have been conceptualized as forms or aspects of 'employee voice', little is known about whether or how collective ADR aligns or interacts with other forms of collective or representative voice.…”
