Employers are obliged to provide a certificate of employment upon employee request for up to ten years after a work relationship has ended. The obligation continues after this period, unless the employer can prove that the letter will be prohibitively difficult to generate. If an employee requests an extended certificate of employment with an evaluation of the employee’s occupational skills and conduct, the employer is obliged to provide it up to five years after the work relationship has ended. If a certificate of employment is lost or damaged, the employer is obliged to provide the employee with a new one.
It is illegal not to provide a testimonial of service. If your employer does not give you a testimonial of service despite your request, you can ask for help from the occupational safety and health authority.
