Abstract
One of the objectives of the presented monitoring study is to examine the influence of organisational and managerial practices on the employees' physical and psychosocial health, as well as to identify causal relationships between different working conditions and staff well-being. The database was formed by conducting a survey in Czech Republic, Kazakhstan, Latvia, Russian Federation and Turkey. Empirical data are analysed by methods of quality two-dimensional projection and design of classification trees. The analysis established causal relationships between toxic organisational factors and respondents' assessments regarding changes in their self-feeling, as well as health consequences.
