(1) The service relationship may be terminated by either party to the contract for a compelling reason without observing a period of notice if facts are given on the basis of which, having considered all circumstances of the individual case and weighed the interests of both parties to the contract against each other, the party giving notice cannot reasonably be required to continue the service relationship until the end of the notice period or the agreed end of the service relationship.
(2) Notice of termination may only be given within two weeks. The period of time commences upon the point in time at which the person entitled to give notice obtains knowledge of the facts relevant for the notice of termination. On demand, the party giving notice must notify the other party, without undue delay in writing, of the reason for terminating the service relationship.
