Globally, more positive outcomes were observed for fixed-term, longer duration, qualification-matching, high wage, and voluntarily chosen temporary contracts (i.e., for compensated and autonomous temporary workers), whereas negative outcomes were more prevalent for agency and casual work contracts, chosen under constraint, with shorter duration, low paid, and matching little the qualifications (i.e., for low-compensated /low-autonomy temporary workers) ( Busk et al, 2017 ; Campbell, 2004 ; Chambel & Castanheira, 2007 ; Dawson et al, 2017 ; De Cuyper & De Witte, 2007 ; Feldman et al, 1995 ; Krausz, 2000 ).…”
