If, on the occasion of leaving employment, a worker requests a certificate stating the period of employment, kind of occupation, position in the business, wages, or reason for leaving (including the grounds for dismissal, if dismissal is the reason for leaving), the employer must deliver one without delay.
If a worker requests a certificate giving the grounds for dismissal during the period between the day on which the worker is given the advance notice of dismissal referred to in Article 20, paragraph (1) and the day of leaving employment, the employer must deliver this without delay; provided, however, that if, on or after the day that the worker receives advance notice of dismissal, the worker leaves employment for reasons other than the dismissal in question, the employer is not required to deliver such a certificate on or after the day on which that worker leaves employment.
The employer must not include any particular in the certificate referred to in the preceding two paragraphs that the worker does not request.
An employer must not collaborate with a third party in advance to communicate any information concerning the nationality, creed, social status, or union activities of a worker, nor include any secret message in a certificate referred to in paragraph (1) or (2), with the intent to impede the employment of a worker.
