upset psychologically if otherwise. At first sight, it may seem to be an attractive idea, but it doesnt bear much analysis. To begin with, people do different kinds of jobs featuring different labor intensity and so the time needed to refresh their physical condition varies. For example, blue collar workers may work longer hours before they get tired physically, while white collar workers such as doctors and teachers are more mentally stressed. Unable to work continuously as long as those physical labor workers, white collars need more time to pull through the mental weariness than physical tiredness. All in all, people in different jobs assume different responsibilities and have different degrees of pressure. Secondly, different tasks and duties are required for different professions, resulting in the variety of holiday periods for people in different walks of life. Some employees cannot have their legal holidays and even have to work overtime, such as policemen, construction workers and people in the service line.Those professions just cant be interrupted for a mornent;other wise the society will be in a mess. Even for some people in the same occupation, they cannot have the same holidays entitled to them due to many factors out of human control, such as special assignments, and health conditions etc, then not to say people in different fields. Suppose we, as teachers do, all have three months holiday in a year. Then factories have to employ considerably more workers because some of them are enjoying happy holiday.Thats obviously against the principles of doing business at lower cost and efficiency. If we have only three days off in a year, then all the people in our country will be working day after day. No one can squeeze time to visit those tourist resorts leisurely. It goes without saying that the tourist trade and catering industr y thus cannot developrapidly and healthily.
