In the English speaking world, the expression a ‘nine-to-five job’ means a normal job. Many people in office jobs 1 from nine o’clock in the morning until five o’clock in the evening, but working hours are different across the world. In some Southern European and South American countries, people work from eight in the morning until one o’clock in the afternoon. They 2 for lunch and then work from four until seven. But these days, many people work from nine to five because these are the working 3 for international business. In many countries, 48 hours a week is the maximum number of hours people can legally work, but many people work more. Many studies show that South Korea and Japan are the 4 where people work the longest hours in the developed world. In Europe and America, people work five days a week and have Saturday and Sunday as 5 . In the Middle East, the traditional holy day is Friday, so the traditional 6 is from Thursday to Friday. This makes international business difficult, so many Middle Eastern countries now take their weekend on Friday and Saturday.
