(Title in Polish - 'Analiza kosztów pracy w ramach zatrudnienia tradycyjnego i elastycznego w relacji do wydajnosci pracy w Polsce oraz innych krajach Unii Europejskiej'). Achievement of higher rates of work efficiency in the Middle-Eastern Europe countries can be reached by creating new workplaces and reducing the unemployment in traditional sectors, being capable of absorbing IT and telecommunication innovations created abroad. It also seems that in long-term time period it is most profitable to invest in human capital. Investments in human capital increase work efficiency, generate raise of employees' income, as well as entrepreneurs' and even countries', and in the end lead to reduction of labour costs. In this area entrepreneurs, as well as the governments should stimulate employees to self-education and increasing professional qualifications which facilitate performance of changing duties. As a result it can enable employees to adapt to changing demands of the labour market. Of course, the assumptions of the 'Green Book' referring to modernization of labour law in order to come up to the challenges of 21st century, are right. Apart from investments in human capital in Poland, it seems that further increase of flexibility on the labour market is necessary. Strict law in employment protection area decreases the dynamics of labour market and worsens employee's prospects. As it was underlined in European Commission's report on employment in Europe in 2006, unintended deregulation of labour market leads to segmentation of labour market and decreases the efficiency of employees. That is why it seems necessary to, at least partially, leave strict frames of traditional employment mode and regulate this area only in necessary range. Such actions can lead to improvement in work efficiency since it is typical - as the researches carried out by the author of this article have shown - that using the flexible employment mode by the entrepreneurs leads to increase in work efficiency.
