'LAM SHIU WAN . 27.How does the shift system benefit the development of;
Hong Kong industries?
Of slightly more than 1 million people at work, in Hong Kong, over 500,000 are engaged in manufactur ing industries. The rapid expansion of industry in Hong Kong has created a demand for trained personnel at all levels. Various methods for the training have been employed to meet the pressing demand for these personnels. As the rapid growth of the local popula- tion the local industries can not absorb the ever
increasing supply of semi-skilled and unskilled work; ers. The factories have to introduce a shift system in order to provide work for them. The factory car use their capital and-land to full capacity and fixed and variable costs can be cut down. Low cost will increase in sales. The maximum use of machinery and factory premises will lower cost of production and the factories can offer a number of better-paid poate on administrative and technical staff. Most factories provide night shift, overtime pay will help the works ers to improve the stardard of living. This system also provides jobs for male workers-working at night. With this system every factory can produce almost double the amount of its out-put. The machinery can be used up to 22.6 hours a day. The fixed cost for the rent di the factory premises will be lower. 138.Explain briefly the methods of calculating wages.
These are different methods of calculating wages: (e)Standard rates according to cost of living,
The standard rates are related to a retail price index by means of a cost of living allowance' based upon it. In Hong Kong some lower paid govern→ ment staff are paid according to this rates. The index is caculated on the basis of a survey batried out in 1948. A base of 100 fixed for march 1947 is used, and the index normally ahowa month by month, fluctuatione reflecting. During 1965 the index fluctuated between 125 and 132. A standard wages saves time and trouble of individual bargaining. It also makes easier the calculation of labour-cost A new consumer price index, conducted by the Commer ce and Industry Department, based on a household expenditure, aurvey,will be replaced the old retail. price index, This system tends to stabilise res) wages at & particular level,
(b)Piece-rates and time-rates.
Under tine-rates a worker receives a certain' Ba per hour; under piece-rates he obtains a certain sm for a given output, Time-rates are used where the work is of a continuous nature, or where the quality of the work 18 important, or where the work cannot easily be standardised and measured, e.g., bus driving, shopkeeping. Piece-rates tends to****
Yout -put, and the costs of supervision, are but the apeed may result in work of poor ty. It also mares easier the calculation of sts of labour. As to the time-rates the slower- and less efficient workers receive same rate of pay It requires careful supervision to prevent slacking (c)Profit-sharing scheme,
Workers are encouraged to take. up shares in the business, or a certain proportion of profit may be set aside for distribution in the form of bonus, usually proportionate to ordinary wageś, The range of daily wages for manufacturing Industry at 1966 wass $9.00 to $27.00 for skille workers; $5.50 to $20.00 for semi-skilled; and- $4.40 to $11.00 for unskilled.
