What do I do if the employer does not accept my sick note or says that he/she did not receive it?
To avoid your employer not accepting your sick note or saying that he/she did not receive it, it is best if you can prove that you have reported sick and handed in the certificate of incapacity to work. You can do this by providing written proof of your sick note (such as sick note by email) and by sending your certificate of incapacity to work to your employer by registered post and in advance as a scan by email. This way, your employer cannot claim that he/she has not received it.
Important: Your employer must accept your sick note. If you are ill and unfit for work, you do not have to go to work.
