Working Hours
The standard workweek is 5.5 days at 8 hours per day, for a total of 44 hours. Work can be extended to 9 hours per day when the work is intermittent or simply requires the presence of the worker, or when the weekly is limited to five workdays.  
Employers are required to provide a lunch break of one hour if food is available on premise, or two hours if not.  
The government mandates one full rest day per week, normally on Sunday, and a complimentary half-day preceding or following the rest day.

Hours worked during the mandated rest day are paid at the rate of 110% of the regular pay. Hours worked during the complimentary rest period are counted as overtime.  
Night work is paid at the rate of 125% of the regular pay   
Overtime is paid at the rate of 150% of the regular pay for the first 30 hours in a week and then at an additional 175% after that.  
The limit on overtime is 2 hours per day, 40 hours per month, and 200 hours per year.
