5. Conclusions
Work engagement is broadly conceived as delivering positive organizational outcomes, and various antecedents have been identified to date (e.g. Khan, 1990; May, Gilson, & Harter, 2004; Saks, 2006; Schaufeli et al., 2002). We have suggested that direct employee voice functions as an important antecedent, generating work engagement based on the principles of the JD-R model (Demerouti et al., 2001): voicing concerns and opinions to influence the work context is a significant job resource. We have focused here on the contextual factors that affect employee perceptions of direct voice practices, which in turn are expected to increase work engagement as a result of the intention-enactment-experience mechanism of employee voice practices (Nishii & Wright, 2008). We have argued that there are both context-free (organizational climate) and context-dependent (LMX and power distance) factors that MNCs should consider when implementing voice practices in different countries. Whilst the context-free factors favor convergence, the context-dependent factors can result in inconsistent outcomes from implementing the same voice practices globally. In pursuing incongruent practices, this can result in employees rejecting them as inappropriate due to their lack of legitimacy in a given context (Paauwe, 2004).
