In general, your employer may only dismiss you during your parental leave in exceptional cases, as you are particularly protected against dismissal by law during this time. This special protection against dismissal begins when you register your parental leave, at the earliest one week before the start of the registration period.
Cases in which this special protection against dismissal does not apply are, for example, the insolvency of your employer, the closure of a business or the closure of a business and in the event of a particular breach of duty by the parent who is to be dismissed.
