In its ruling dated 29.05.2025, numbered 2025/3201 E. and 2024/1108 K., the 9th Civil Chamber of the Supreme Court held that, in determining the periods that serve as the basis for annual paid leave and severance pay, the time an employee spent on unpaid leave during the pandemic under the scope of provisional Article 10/2 added to Law No. 4857 should be taken into account, provided that it does not exceed the duration formed by adding six weeks to the statutory notice period. Any period exceeding this limit shall not be included in the calculation of the service period.
