The aim of this research is to observe the tendencies and inclinations of women for volunteering and social work. As the research question implies, we are focusing on the case study of a pro-migrant organization Mareena located in Slovakia. Even though Slovakia does not struggle with great amounts of refugees coming to the country, there is a migrant community that requires tolerant and respectful approach, help and guidance. This is the main reason why Mareena was established in 2015 after the migration crisis outburst. The organization led exclusively by women seeks to assist the refugees on their way to integration and assimilation to the new country and its culture. Activities similar to these are crucial, especially in the countries like Slovakia where the fear of the unknown is significant. Slovakia is considered a religious and traditional country, therefore, the perception of refugees is not positive. The goals of Mareena are met with the help of discussions, various projects, cultural events and other activities where local people have the opportunity to meet with foreigners and observe what the similarities between them are. This way, the organization is trying to minimize the gaps between them and build “bridges” that connect everyone. We initiate this thesis with a hypothesis assuming that women indeed have a bigger tendency to work in the social work sector. This thesis offers a theoretical background of the NGOs, volunteering, social work, the functioning of organizations helping the refugees but most importantly it investigates the role and the importance of women and their engagement in the third sector. After the literature review of the themes mentioned above, the research will be extended by the practical part consisting of interviews with employees and volunteers of Mareena. Those interviews allow us to acquire an insight into the organization, its work environment and the realities of the women employed in the third sector. Afterwards, the thesis continues with an analysis of the given interviews where we take a closer look at the opinions and perceptions of their activities and position within the non- governmental sector. The thesis attempts to discover whether there are unequal ratios of women and men in this sector, whether one of the genders is more prone to this kind of career and if so, what are the influences and reasons for it. At the end of the research, the reader should be acquainted with the background information about the NGO sector, the engagement of women in the third sector and the results of our research based on the combination of the primary and secondary sources. This data collection should aim to answer the initial research question.
