What Is the Notice Period?
Definition
Notice Period (İhbar Süresi): The time one side must give the other before ending an open-ended employment contract. It grows with the length of service, and the side that skips it owes notice pay.
The notice period is the warning time one side must give the other before ending an open-ended employment contract. Labour laws usually set it by length of service: the longer the worker has served, the longer the notice. The side that ends the contract without giving it owes notice pay for the missing days.
Where it appears in the formulas
notice days = weeks × 7 and gross notice pay = (gross wage + benefits) / 30 × notice days. The notice pay calculator turns the weeks of notice into days and multiplies them by the daily wage with benefits.
In Türkiye
Labour Law 4857 art. 17 sets the notice period by service: 2 weeks under 6 months, 4 weeks up to 1.5 years, 6 weeks up to 3 years, 8 weeks beyond. A worker with 3 years 6 months of service and a gross wage of 50,000 TRY has 8 weeks, or 56 days, of notice; the gross notice pay is 93,333.33 TRY. With 4 months 24 days of service the period is 2 weeks and the gross pay 23,333.33 TRY. At the limits, the calculator counts exactly 6 months of service as 4 weeks, exactly 1.5 years as 6 weeks and exactly 3 years as 6 weeks; 8 weeks start one day after 3 years.
