According to Section 59 Para. 1 Sentence 1 BAT, the employment relationship of an employee ends at the end of the month in which a notice from the pension insurance provider about his reduced earning capacity is sent to him, provided that the employee receives a pension outside the statutory pension insurance, to which the employer has contributed. If the employee is severely disabled in the sense of SGB IX and is at the point in time at which the employment relationship is terminated due to reduced earning capacity in accordance with Section 59 Para. 1 BAT ends, if the consent of the Integration Office required according to Section 92 SGB IX has not yet been received, the employment relationship ends in accordance with Section 59 Paragraph. 4 BAT at the end of the day on which the approval notice is delivered. Continuing its previous jurisprudence, the Seventh Senate decided in its judgment of March 15, 2006 ( 7 AZR 332/05 ) that the delivery of the notice from a pension insurance provider granting an unlimited pension due to partial disability in accordance with Section 59 Para. 1 Sentence 1 BAT also leads to the termination of the employment relationship if, in addition to the permanent pension due to partial reduction in earning capacity, the employee is granted a temporary pension due to full reduction in earning capacity. Such a decision does not cancel the decision approving the permanent pension due to partial incapacity, so that this has the legal consequence of the termination of the contract in accordance with Section 59 Para. 1 set triggers 1 BAT. The employee can only terminate the contract in a formal and timely manner. S. of § 59 para. 3 last half sentence BAT prevent the application for continued employment submitted to the employer. The employer is not obliged to inform the employee of his own initiative to comply with the provisions of Section 59 Para. 3 BAT prescribed form and deadline for the application. In principle, an employer’s appeal to non-compliance with these regulations does not violate trust and faith (§ 242 BGB). Something different applies if the non-compliance with the form and deadline was caused by the employer, e.g. B. if the employer prevented the employee from submitting the application for continued employment in writing. If there is no proper application for continued employment, the employment relationship ends due to the conditions set out in Section 59 Para. 1 sentence 1 BAT standardized subsequent condition according to § 21, § 15 para. 2 TzBfG at the earliest two weeks after receipt of written information from the employer about the occurrence of the condition.
