At the end of your employment you are entitled on request to a written certificate from your employer specifying how long you were employed and the nature of your duties. If you so request, the certificate of employment must also state the reason why your employment ended, and include a testimonial to your ability and conduct.
The employer’s duty to issue a certificate continues for ten years after the employment ends, but a certificate that includes a testimonial to the employee’s ability and conduct must be requested within five years of the end of employment.
