The maximum number of working hours in one week in Turkey is 45. Subject to the agreement of all parties, the total working hours can be apportioned in different combinations per working day, provided that the working hours do not exceed 11 hours a day. 

Any time beyond the established 45 hours is considered overtime. Overtime may not exceed 270 hours per year. Overtime rates involve a 50% daytime premium on weekdays and Saturdays and 100% on Sundays and public holidays.
