Even in the 21st century, the term of family business is still absent, although up to 80% of companies in Slovakia fall into the category of family businesses. Following the evaluation of the current position of family business in Slovakia the aim of the diploma thesis was to identify the key strengths and weaknesses of family businesses that affect their development and to propose the measures to support existing and emerging family businesses in Slovakia. The theoretical part pays attention to the specificities of family business, definitions of family business and also their strengths and weaknesses. We prepared an anonymous questionnaire, which we used as a basis for mapping the current position of family businesses in the business environment of the Slovak Republic. The questionnaire was transmitted by electronic means. Subsequently, we evaluated the obtained results by means of statistical methods, graphs and texts. The conclusion presents proposals for measures that, after implementation in practice, could significantly help family businesses in Slovakia.
