Abstract
In this chapter, the author presents the problem of the protection of whistleblowers’ personal
data in the workplace in connection with the processing of their data in the channels for
reporting breaches in the context of the transposition of the Directive on the protection
of persons who report breaches of Union law into Polish law. The existing regulations ensure
limited protection for employees and other individuals against retaliation or violation
of privacy. The author postulates the necessity to develop comprehensive whistleblower
legislation. The purpose of the legislation will be to oblige the employer to develop and
implement solutions that will guarantee genuine confidentiality and protection of whistleblowers’
personal data.
