Although, they feel this method will help them to reduce to spend salary or wage expenditure to employ extra full time labors to assist them to achieve to raise aim of productivity. But in fact, they neglect to consider other disadvantages to cause their labors to feel tiring and unfair treatment and reduce their standard of life, due to their labors will not increase salary or wage very much and who also need to work very long hours per working day. I shall indicate evidences to prove why abnormal work hours method can only raise productivity in the short term, but this method can not raise productivity in the long term and it can also influence overall society economic decline and it can also influence labors' standard of life to be poor. In the final, I shall also recommend how employers, such as Hong Kong and China employers how to change their methods to achieve to raise their productivity in the long term.
