Modern technology and artificial intelligence are increasingly being used in labour relations. Technological solutions support employers in managing the organisation, reduce the cost of supervising the work process, and enable easier and faster control of employees’ work. However, the use of technology, especially without sufficient human supervision, raises risks in the area of employees’ right to privacy and data protection. Not only can it risk violating data protection laws and lead to violations of employee privacy, discrimination or even dehumanising working conditions. The article aims to identify the potential risks to the protection of employees’ personal data in connection with the use of high-tech solutions and artificial intelligence in labour relations, and the obligations of the employer of data processing, in accordance with the principles set forth by the RODO.
