(44)There should be a close link between reporting and the adverse treatment suffered, directly or indirectly, by the reporting person, for that adverse treatment to be considered to be retaliation and consequently for the reporting person to be able to enjoy legal protection in that respect. Effective protection of reporting persons as a means of enhancing the enforcement of Union law requires a broad definition of retaliation, encompassing any act or omission occurring in a work-related context and which causes them detriment. This Directive should not, however, prevent employers from taking employment-related decisions which are not prompted by the reporting or public disclosure.
