  • Employee monitoring in the modern business services sector

    As the modern business services market continues to experience explosive growth in Poland, it is worth keeping in mind the legal issues surrounding practices related to monitoring of employees. The line between lawful and unlawful monitoring practices is at times unclear, and issues of personal data protection also must be kept in mind.
