The article investigates a strategy used by a Polish subsidiary of a multinational corporation to improve the professional skills and knowledge potential of its workers through a system of vocational training courses. Vocational education and training (VET) is one of the basic mechanisms of transferring and generating knowledge in enterprises and a key factor of competitiveness in a knowledge-based economy under globalization. The use of the case study method results from the need to complement analyses conducted in this field with the latest empirical findings concerning enterprise-level processes. The case study is also an example of a wide spectrum of methods used by enterprises controlled by foreign investors to improve the professional skills of workers. The analysis corroborates earlier findings by many authors about a stronger embeddedness of foreign investors in regions where they have established cooperation links with local partners.
