The objective of the paper in this context is to emphasise those traits of character which should be found in good leaders and which make them more efficient. Methodology. In order to identify the key traits a leader should have, a factual study was conducted among 156 employees working for different businesses. The study was conducted using an anonymous questionnaire. The second research technique was a direct individual interview with the CEOs from 5 different companies.  Key findings. The study identified a group of key conditions that significantly influenced the building of the degree of employees’ involvement and contributed to enhancing the body of knowledge in the companies. The study indicated the following subjects: the employer-employee relationship, the role of employees in the decision-making process, their expectations, and the adopted style of leadership in the company. The obtained study results allowed to form a more practical view of the concept of leadership. According to the company’s CEO, the effectiveness of leadership largely depends on the adopted managerial style.
