The paper discusses the effectiveness of introducing criminal sanctions for violations of provisions implementing the Directive on improving working conditions in platform work. The analysis includes the obligation to establish “effective, proportionate, and dissuasive” penalties, provided in this and other labour law directives and the possibility to choose criminal sanctions to this end. The paper also examines the current practice of implementing criminal sanctions in Poland, highlighting such issues as low fines and limited deterrence. Challenges related to the place of committing a crime and the criminal liability of AI in algorithmic management systems are dis[1]cussed. The conclusion suggests that the perspective of introducing criminal liability for breaches of the Platform Directive is a complex issue, requiring a comprehensive discussion on the system of criminal labour law in Poland.
