It needs to be announced in writing until the last calendar day of the current month. This means that your membership will cease at the end of the month following your formal notice.
For example, you want to work in another office from the 1st of October. Inform our team the latest by August 31 about your intentions. Once you have contacted us you will receive a confirmation of our service team that the move must be held by September 30 at the latest. Of course, you can also vacate your workplace or office earlier. In any case, the last calendar day of each month is the last possible move-out date.
