Abstract
The analysis of employment structure is a very important issue in the companies and it is connected with many factors in the company and on the market. An interesting issue is whether labour efficiency affects economic and financial performance of the company and the whole market. In the case of any statistical regularities concerning this issue it is necessary to allow for the variables related to employment, e.g. in the analyses of listed companies. It is a particularly important matter in Poland where the ownership transformations and transition to market economy have resulted in major changes in employment in individual companies. The main goal of the paper is an analysis of the structure of companies by their group labour productivity in homogenous groups of listed companies, the so called megasectors, in relation to their economic and financial condition. The study refers to the period of 2000-2003 and includes 73 companies listed on the Warsaw Stock Exchange.
