Requirement of equal treatment in employment and the prohibition of discrimination against workers is due to both the provisions of the Constitution, the Labour Code, the Civil Code, the Penal Code and the provisions of European and international law. Discrimination occurs when an employer treats a comparable situation of workers in different ways. The most common discrimination is the one based on age, gender and disability.

Nowadays organisation of work time often involves shiftwork, which affects workers'''' health.
This article analyses recent reports on the influence of shiftwork on the risk of carcinogenesis. It presents various definitions of shiftwork and the scale of the problem. It also discusses the latest research on the association between risk of breast, endometrial, prostate and colon cancer, and shiftwork.  According to the position of the International Agency for Research on Cancer IARC, shiftwork that involves night work resulting in disturbance in the circadian rhythm is a potential carcinogenic factor, class 2A. Despite the sufficient evidence coming from experimental research performer on animals for the cancerogenicity of light during work  at night, there is still limited evidence for the carcinogenicity of shiftwork at night performer by humans. We conclude that  further research should focus on preventive strategies.
