“…Accordingly, temporary workers may not feel the need to turn to the union in the face of job insecurity. In line with this reasoning, previous studies have demonstrated that felt job insecurity does not relate (as strongly) to strain among temporary workers (compared with permanent workers) (Bernhard-Oettel, Sverke, & De Witte, 2005;De Cuyper & De Witte, 2006Klandermans et al, 2010;Mauno, Kinnunen, Mäkikangas, & Nätti, 2005). Hence, frustration with job insecurity may not be the driving force for unionization among temporary workers, while it is among permanent workers.…”
