Why should someone work? That’s obviously to bring happiness into ones’ life. But how will that be possible if a person keeps working all day? Most of the government and private companies have fixed just 8 hours of working time and they are paid for it accordingly. When was this pattern fixed? By the end of 18th century, and initial days of 19th century, people used to work for 12 to 18 hours, and in fact, there were 20-hour work pattern too. There were protests to cut it down to 10 hours. Following this, the first of May was announced as the International Worker’s Day.
