Am I violating my employment contract by entering my salary?

Employers often declare salary information as a "business secret" in their internal regulations, which can sometimes be justified, and sometimes not. According to the Law on the Protection of Confidential Information (Article 19, Paragraph 2), it is stipulated that an internal regulation cannot declare all information related to the operations of a legal entity as a business secret, nor can information whose disclosure is not reasonably contrary to the interests of that legal entity be declared as a business secret. Therefore, if an employer decides to declare salaries as a business secret, we cannot know whether the employer has a justified reason for doing so or if it is a general declaration without any reasonable business justification. However, we can conclude that there are many professions and job positions where salaries are publicly disclosed, such as those employed in public and state services (by prescribing and publishing coefficients and bases for specific job positions), regardless of the potential sensitivity of these professions and job positions, and regardless of the potential business interests of these bodies and legal entities.
‍
Therefore, regardless of whether the employer has a justified interest in claiming that the salary represents its "business secret," the interest of workers in disclosing salary ranges for their job positions will always be diametrically opposed to the interests of the employer. One of the fundamental principles of the Labor Law is that equal pay should be given for equal work. To realize this principle in reality, it implies that workers must have access to the bases and criteria for salary payments for their job positions, i.e., the necessary level of competencies for a particular job position, which workers cannot know without first being aware of the salaries of other colleagues employed in the same/similar job positions with the same/similar competencies at other employers in Croatia (or abroad, if data is available).
‍
Therefore, the purpose of the Tabu platform is to allow anyone who wants to know the approximate salary amounts for their job position in Croatia (and abroad, if data is available), and if the information about their current salary is not a business secret, or if it is, but the workers, regardless of that (for any reason), believe they have the right to provide such information to the Tabu platform, they can do so. On our end, we will guarantee the maximum security and anonymization of such data in a way that the provision of such information cannot be linked to any specific person and ensure that such data is never published anywhere.
