The Supreme Court’s decision of 30 September 2025, Case No. 21 Cdo 1325/2025, significantly clarified the interpretation of employers’ obligations in the area of occupational safety and health (OSH). Specifically, the decision applies to all employers using external workers (e.g. cleaning services, technical services, etc.).
The Supreme Court dealt with a case where an external worker (self-employed), hired through another company, performed a subcontract for cleaning in a transformation plant. The external worker was not trained on the risks and safety rules of the facility before starting work. This resulted in the use of unsuitable work tools, leading to a serious electric shock.
The company denied its responsibility, arguing that the external worker was under contract with another entity and the obligation to properly train the worker rested with the direct contractor.
The Supreme Court, however, rejected the company’s argument outright. It stated that the employer has a duty to ensure the safety not only of its own employees but also of all persons who are on the premises of the workplace with its knowledge. It is irrelevant whether the person present at the workplace is performing activities independently, in their own name and on their own account and responsibility.
It also explicitly stated that the obligation to ensure OSH cannot be contractually transferred to another entity. If the employer allows an outsider to enter the premises, he is responsible for his safety and must ensure that such person is properly informed, trained and protected.
