when does the work week start and end
Workweek and weekend The workweek and weekend are those complementary parts of the week devoted to labour and rest, respectively. The legal working week (British English), or workweek (American English), is the part of the seven-day week devoted to labour. In most of the Western world, it is Monday to Friday; the weekend is Saturday and Sunday. A weekday or workday is any day of the working week. Other institutions often follow the pattern, such as places of education.
35-hour workweek The 35-hour working week is a measure adopted first in France, in February 2000, under Prime Minister Lionel Jospin's Plural Left government. It was pushed by Minister of Labour Martine Aubry.
