The article is devoted to the study of the social psychological peculiarities of workers whose behaviour deviates from the rules and norms set by the legal regulations. More than 1,000 employees of the enterprise aged 25-50 years were surveyed, of whom 400 were identified as "violators" of organisational and production discipline, occupational health and safety, 600 people were classified as law-abiding workers. A set of 3 methods was used, aimed at analysing the social psychological characteristics and studying the interrelations of the multi-level personality characteristics of the employees of the enterprise. Analysis of the results made it possible to describe the social psychological portrait (personal characteristics) of persons with deviating labour behaviour. The following personal predictors of deviating work behaviour were identified: respect, above all, their own interests, rather than group ones; low level of cooperation, a pronounced desire for dominance, a focus on avoiding failures, adaptability to breaking the rules; as well as alexithymia and other characteristics. The results of the research contribute to the optimisation of the management of labour compliance, industrial safety and labour protection of enterprises with high risk environments of production environments.
