The employer may have employees work in excess of 40 hours in a specified week or in excess of 8 hours on a specified day.
      • Flexible Working System – Also called Flexi system, allows for working hours to be adjusted within a monthly period. Under this system, the total number of working hours that an employee must work during a fixed period of not more than 3 months is established, and the employees are free within limits to determine what time should be the starting and ending time of work, provided that the total number of working hours required are met.

Any work in excess of 8 hours a day or 40 hours a week, or on holidays, requires an advance written agreement between the employer and the relevant labor union. The “36 agreement” is usually in the form of a standard one-page contract that is stamped by the employer and employee representative and filed with the local labor office.
