The notice period does not include so-called protection periods, for example maternity leave or sick leave. See section 53 for the full list of reasons why an employee is protected. During this time, an employer cannot dismiss you. However, if you are dismissed from your position before the protection period, the termination period recommences after you return to work. So if you are fired, and after the first month of the two month termination period passes, you fall ill and have time off work, you can return to work for another month after your sick leave to complete the termination period unless you request otherwise. In other words, you would be submitting a ‘termination by agreement. It’s conceivable that you could submit such a request during an ordinary two-month termination period too.
