1. What are. the functions and work of the Labour Department? Explain the part.played by this Department in improving the relationship bet tween Employers and Employees.
Answer:
The existence of the Labour Department serves several main.. functions. To realize the funct- rons fo thre Department is easy if we look into its structure.
·The Department is composed of sax divisions: - Industry division, Employment division, Industrial Health division, Industrial Train ing and Development Division, La- bour Relations division. Each division has its clear and dis-g tinct function.
The Industry division 13 res- ponsible for the: safety of workers in factories and industrial under- takings. This division often sends out inspectors to factories"to ensure that factories provide: adequate safe working conditions. This division is further reinforc ed by the factories and Industria Jndertakings Regulations which provides for safety measures in.. the use of woodworking machinery,
who
The Employment division suppli es information to job seekers, - look for working opportunities locally and abroad. The Local Employment Service arranges :place- ment for job seekers and employers to meet que another. Young school Leavers are also benefitted by this division. Careers pamphlets are published and obtainable from. the Youth Employment Advisory: Service. These pamphlets are quite valuable to the youngsters for they supply relevant information: regarding the choice of career. Besides, career talks and convent- ions are
the int arranged. These arouse
of the students in: their own future. Local workers seeking for jobs abroad can obtain: help from this division concerning the working prospect and applicat- jon procedurer
Health condition of the workers. must be well. protected before. they can make full use of their effic- jency. The Indust mal Health Divi
el on: advises the Government and industry on the prevention of pccupational diseases. Workers, exposed to risks of lead and radi ation have to undertake medical examinations: annually. This measury is necessary to guarantee that . workers rn the related fields are free from 'the attack of radiation. In jured workers, need to be examin
ed clinically by this division.
Industrial Training division 19 responsible for the promotion of technical skill and training of right persons in the appropriate industries. A number of pre-vocat- ionál and vocational training centres are operated by voluntary welfare organisations and the Government. These centres provide training in technical, commercial and catering trade. Employers are
-ncouragea to adopt apprenticeship schemes for training craftsmen" The Hong Kong Polytechnic and Morrison Hill Technical Institute provide part-time day-release courses for both craft and techni aian apprentices. The above ment-. ioned efforts are aimed at promot- ing the technical standard in Hong Song
Industrial disputes are bound to arise between, employers and Kemployees. This will hinder smooth -ness of production. So it is im- portant that both parties mist be patient and tolerant. Or else, this will result in a loss to both sides. Sometimes, they may be so extreme that no agreement can be arrived at. This calls for the Labour Relations Division to step in Officers from this division act as intercessors. Intercessors ali try to persuade each party to co-operate so as to arrive at 1 conclusion. Very often, with the help of labour officers agreement can be reached easily. Definiteiv. this division contributes much cn promoting thes mutual understand wing of both employers and workers

2. (a) What is the significance of annual budget on the local economy?
Answer:- The financial year starts
on the 1st April of each year and ends on the 31st March of the next year. Before the next finan- cial year starts, the Financial Secretary will present a list of
·expenditure and revenue estimates of all Government Departments in the Legislative Council. This list of estimates is known as Annual Budget. The Budget is important for it forecasts the future trend of the economy. Any significant increase in expenditure of a
department has to be examined carefully. The head of that depart mment has to explain the reason" of such significant increase. The public is particularly concerned with the annual budget. Should there be any increase in taxation.. this wi11 arouse the interest of the general public. The Government is taking the lead in deciding the future of the economy. It may
happen that the way how the Govern 一ment: spends its money will stimul: -ate or discourage investment from local and foreign investors. They deem the action of the Government to be important in deciding their own policy.
Annual Buaget has certain econ omic significance. It can be used as an instrument of economie.
policy to stimulate recovery from a trade recession, In times of business depression, businessmen: are not willing to undertake long- term projects. It should responsibility of the Government. to stimulate recovery. This can be achieved by adopting a policy known as: "deficit financing": Ideally, the Budget should be so prepared that there should be neither a large surplus nor a.. large deficit. In case of depress- ion, the Covernment should deliber
-ately. increase the amount of
expenditure. That is to say, the Government should take the lead: undertaking large-scale public works. This will restore the :con− fidence of businessmen on the economy.
Annual budget can be used as tool to fight: against inflation, This is done t by increasing the. level of taxation so that a larger. surplus is obtained. Again, it is a useful tool to reduce inequality of income. In order to achieve this aim, the Government has to adopt a steeply progressive income tax. That is to say, the rich should be taxed more heavily.
Further more, inequality of income is reduced by the provision of
social services. This will benefit
the poor more. Another purpose of Annual Budget is to help the"
balance of payments. Certain.im ports can be discouraged by impos− ing duties on particular imports. This will result in the curtailing the demand for these goods.
(b)
Answer:- Taxes are of two main types, namely direct taxes and
inda.rect. taxes. Examples of darect
taxes are income tax and profits. taxes. Sales tax and entertainment:
examples of indirect tax.
res. th one way. For direct:
"taxes. tax impact and tax inciden
ce are on the same person. Whereas for indirect taxes, tax impact
and tax incidence may not fall on the same person. Tax impact is on the person who first receives the tax burden. If he can shift. thei tax impact to another individual, that sort of tax will be known as indirect tax. The incidence of a tax is upon the person who pays. it Fo .come tax the incidence.. is always on the person receiving the income for income tax cannot be shifted to someone else. In the case of indirect tax, tax in- pact and tax incidence may not fall on the same person. For example, if a specific tax of $20. le imposed on an electric heater
