At least four weeks before the leave is due to commence, the confirmation document' specifying the date of commencement of the leave, its duration and how it is to be taken, must be prepared and signed by both you and your employer.
Once the 'confirmation document' has been signed, you are entitled to take parental leave at the specified time.
After the confirmation document has been signed, both parties can agree to change the arrangements and a new confirmation document setting out the revised arrangements must be drawn up. However, the employer is not obliged to change the arrangements.
