The aim of this study was to analyse whether the social exchange between temporary agency workers (TAWs) and the client organization is associated with a perception of training. In this study, we developed and tested a moderated mediation model that accounts for TAWs' exhaustion and desire to obtain a direct contract with the client company in the relationship between the perception of training and affective commitment. Our hypotheses were tested on a sample of 425 blue-collar workers from four Portuguese companies with temporary agency work contracts. Our findings support a conditional indirect relationship between the perception of TAWs that the training provided by the client company facilitates their internal employability and their commitment towards this company via exhaustion for those TAWs who have a low desire to have a direct contract with this company. In addition, our findings show that TAWs do not reciprocally respond to the training that promotes external employability, as this factor is not associated with the affective commitment of these individuals, although exhaustion is associated with this perception. Moreover, we discuss the implications of these findings for the human resource management of TAWs.

The development of either internal or external employability of temporary workers has been considered a mechanism of protection since it ensures that employment can be maintained. According to the social exchange theory and the norm of reciprocity, when temporary workers perceive that the training promoted by the organization furthers employability, they are inclined to feel obligated to reciprocate with positive attitudes toward the organization. With a sample of temporary agency workers from three distinct industry organizations (N = 279), the current study investigated the relationship between training that promotes both internal and external employability and affective commitment as well as the role of voluntariness as a moderator of these relationships. The hypotheses were tested by using regression analysis. The results indicated that the perception held by temporary workers that the training they received is a promoter of their internal employability is positively correlated with their affective commitment towards the organization. Furthermore, the data revealed that this relationship is weaker for the group of temporary workers with high voluntariness. On the other hand, there was not a significant relationship between the training that promotes external employability and the affective commitment of temporary workers. Likewise, voluntariness did not moderate this relationship.
