This article highlights the critical importance of the supervisory board in modern corporate governance mechanisms. Such mechanisms have become prevalent in many European countries, where they define the role of the supervisory board as an independent overseer, focused on monitoring the activities of the executive body.
 The wide range of duties and competencies of the supervisory board is discussed, including strategic planning, oversight of executive directors, consideration of corporate decisions, and ensuring adherence to corporate standards. It's crucial to note that the primary mission of the supervisory board is to protect shareholders interests, guarantee their rights, and ensure transparency in the actions of the joint-stock company.
 One of the key challenges the author examines is the dilemma of how executive managers perceive the supervisory board. Do they see this body as an ally that enhances work efficiency or as an obstacle in the way of making operational decisions? This aspect is vital for understanding internal corporate relations and the dynamics of interaction between management structures.
 The article also focuses on the OECD principles regarding corporate governance, emphasizing the importance of an effective structure of the supervisory board. Particular attention is given to the role of independent non-executive members of the board, who can act as a «braking mechanism», ensuring objectivity, independence, and a critical perspective on corporate decisions.
 In conclusion, in the corporate governance of joint-stock companies, the supervisory board emerges as a key element playing a strategic role in protecting shareholders' interests, ensuring transparency, objectivity, and accountability in company operations. The OECD principles underline the significance of including independent members in the supervisory board. This stance affirms the necessity to amplify the role and authority of the supervisory board in contemporary conditions, making the exploration of this issue particularly relevant and significant.
