AThe matter of openness of pays is one of the key characteristics of a salary system. Psychological theory, confirmed by results of numerous analyses and experiments, shows quite explicitly that height of pays received by employees should be made public due to keeping possibly highest motivation for work. Nevertheless, the majority of managers takes an opposite direction. Influenced by the specificity of the labour market, the necessity to fight for employees and the care of keeping balance of firm finances, they tend in practice to keep secrecy of employee's salary height. The aim of this paper is to provide an analysis of psychological aspects of salary's openness and of the implications of its application in practice, and, in consequence, an attempt to answer the question: should and on what conditions, the heights of salaries be made public.
