“…Also, when collective bargaining is defensive, the union may play a role in the processes of skill formation (Klindt, 2017; Pulignano & Stewart, 2013), for example through the promotion of employees’ re‐training programmes. In addition, unions may engage with training decisions becoming training providers and participating with other stakeholders in middle‐level institutions in the design and implementation of training programmes for the local labour market (CNEL‐Istat, 2015; Cooney & Stuart, 2012; Del Punta, 2003; Kristensen & Rocha, 2012; Trampusch & Eichenberger, 2012), possibly widening the audience of recipients towards the inclusion of low‐skilled workers (Hoque & Bacon, 2008; Lindsay et al., 2012; Wiß, 2017). More indirectly, workplace unionization may be associated with longer tenure (Boockmann & Steffes, 2010; Busemayer & Trampusch, 2012; Estevez‐Abe et al., 2001; Hirsch et al., 2010; Pfeifer, 2011) and bolster the integrity of internal labour markets (Harcourt & Wood, 2007), thus creating incentives for long‐run human capital investments (Lazear, 2009).…”
