Conclusions
In conclusion, the present study has illustrated how different internal and external conditions among the SMEs and HRIs, the process of engaging with an HRI, and the types of HR services delivered, are important for understanding the relationship between SMEs and HRIs and the factors that enable or restrict the outsourcing process of HR services. Concerning the theoretical contributions of this study, we would like to emphasise that it provides an enhanced understanding regarding the relations between SMEs and HRIs, based on the two broad types of SMEs (with low/high internal HR skills) and two types of HRIs (with short/long-term orientation). This type of simple categorisation makes it possible to identify a large and potentially vulnerable group of SMEs, namely SMEs characterised by low internal HR skills that buy HR services from short-term oriented HRIs. On a broader level, it also seems evident from the findings presented here that we need to question and rethink some of our theoretical understandings of what constitutes an organisation and its employees, and how different types of organisations relate to each other. In yesterday’s labour market, it was reasonable to assume bilateral and more predictable relations between labour market players, but with the introduction of HRIs, this has changed in many respects. Organisational limits are displaced or dissolved, not all employees necessarily have the same employer, and the work of HR is not necessarily performed in-house. Bilateral relationships become trilateral, resulting in a more complicated setting. In line with Bonet et al. (2013), it can be argued that we may be facing a paradigm shift, where the reality can no longer be understood from the existing models.
