Nowadays, the services sector is most effective as translating productivity growth into employment growth in Hong Kong. The HK Government forecast (2012) indicated that "HK's economy has slowed, growing by 0.9% year-on year in the half of 2012 year, after expanding by 5% in 2011 year. For 2012 year, the economy is forecast to grow at 1-2%. Consumer prices increased by 5.3% in 2011 year and 4.7% year-on-year in the first half of 2012 year. The unemployment rate was 3.2% for April-June 2012 year, compared with 3.4% for 2011 year." Although, it seemed that unemployment rate decreased 0.2% for April to June 2012, but its unemployment was still existed. Moreover, HK's economy has slowed to grow by 0.9% only year-on-year in the first half of 2012 year and HK government forcast to grow at 1-2% for 2012. By United States Government statistic in 2006 year, the average man employed full time worked 8.4 hours mandatory minimum amount of paid time off for sickness or holiday. However, regular full time workers often have the opportunity to take about nine days off for various holiday. However, regular full time workers of skill leave and two weeks ( 10 business days) of paid holiday time with some workers receiving additional time after several years. Because of the pressure of working time with some workers receiving additional time after several years. It seems United States developed countries some workers still feel pressure of working shorten working hours can reduce the pressure of working. In fact, HK many professional workers put in longer hours than the forty hour standard per week. A forty hours work week is considered inadequate and may result in job loss or failure to be promoted. Although, these employers don't spend much salary expenditures to employ extra professional workers to share whose workload and who can perform to serve whose clients efficiently in the short time. But in the long time, it is possible that who will work pressure possibly due to who need to serve many clients every day, and whose working performance will become to be poor to cause inefficiently. Until now, HK has no legislations regarding maximum and normal working hours. The average weekly working hours of full time employees in HK is 49 hours. According to the Price and Earnings report (2012) conducted by UBS, when the global and regional average were 1,915 and 2,154 hours per year respectively, the average working hours in HK is 2,296 hours per year, which ranked the fifth longest yearly working hours among 72 countries under study. In addition, the survey is conducted by the public opinion study group of the University of HK, it showed 79% of the respondents agree that the problem of overtime work in HK is "serve" and 65% of the respondents agree that the legislation on the maximum working hours. In HK, 70% of surveyed don't receive any overtime remuneration. These show that people in HK concerns the working time issues. The equilibrium price for a certain types of labor is the wage rate. The model of labor market, even given all its assumption is logically. The criticism of application of the model of supply and demand generalizes particularly to all markets for factor of production, e.g. labor working hours. I assume HK employers don't like to employ many labors to assist current labors to raise service or productivity when their client numbers have increased. It is possible that who feel salaries expenditure can not be exceed to their reasonable budget. Hence, who need current labors to work long time hours to do too much work, even the HK labor supply is increasing and it will cause many people lose jobs. It seems HK service industry can influence its economic growth.
