The article analyses selected provisions of the Artificial In­telligence Act (AI Act) concerning employers’ obligations related to the use of AI systems in the workplace, taking into account the employer’s role as a provider or a deploy­er under the Regulation. It seeks to determine whether the mechanisms adopted, including risk assessment and system classification, oversight requirements, information duties, and the Fundamental Rights Impact Assessment (FRIA), ensure effective standards of safety and respect for workers’ rights, or whether, due to the specific features of the employment relationship, they may prove of limited effectiveness.
