Research questions: The objectives of this study are to identify the need for Social Enterprises (SEs) as an alternative form of working in the Finnish labour market, what alternative forms of co-operation between such types of SEs could be and how larger local companies can support the sustainable operation of these small SEs by employing immigrants and the long-term unemployed. Theory: This article draws on the corporate social responsibility CSR theory of traditional enterprises to better explain the factors that can facilitate co-operation between SEs and private enterprises, thereby reaching the sustainable operation of SEs that are run by socially disadvantaged groups of people in Lapland. Phenomenon studied: SE is a new phenomenon in Lapland. There are a few SEs in the region that are struggling to maintain their existence in a sustainable manner. It is harder for the members of such SEs to run businesses or to work and to become successful in Lapland; however, obtaining employment or running a proprietorship is not an alternative (Yeasmin, 2016) for these disadvantaged people. Case context: The article contributes to the studies on the economic integration and labour market sustainability of immigrants and long-term job seekers, and particularly to the socio-economic integration of the long-term unemployed by focusing on the necessity-driven social entrepreneurship networking model in a sparsely populated region, that being the region of Lapland in Northern Finland. Findings: The disadvantaged groups need access to the labour market in Lapland, and social alliances between various partners (e.g., private, public and SE) under different social circumstances (e.g., CSR) can generate alternative options for co-operation to sustain the existence of such SEs in Lapland. An analysis explores future recommendations for co-operation that might sustain SE’s existence and development and might also increase long-term prospects for targeted SEs. Discussion: Lapland-based SEs operated by immigrants or the long-term unemployed are issues and themes that do not fall within the responsibility of any single authority or any single sector. Successfully running SEs demands positive interaction and social innovation strategies among many social partners. Networking with a variety of public stakeholder groups alongside the private sector needs to see an investment of social resources for mapping the phenomena on the topic of social economy, which is a social innovation process that might enable such SEs to have successful outcomes in Lapland.
