Since the employer will no longer have the right to ask about previous remuneration, how should it be treated if the employment record statement provided by the employee before starting work shows remuneration from previous employers?

The employer does not have access to this information and cannot request such a statement from the Employment Register on its own. Only the employee can request such a statement and specify exactly what information they want to be included. If the employee chooses to include remuneration information, this is not information requested by the employer, but rather the employee’s personal decision.
