HUMAN RESOURCES MANAGEMENT

Human Resources Management (HRM) is the process of managing people and their relationships in an organization. These two processes are important in the success and growth of a business.

In managing people, staffing is the most important component of HRM. It needs to make guidelines and procedures for hiring and placement. Staffing also involves the management of employees on matters like monitoring of holidays, absences, health and safety, disciplinary action, and dismissal.

Another important element of HRM in managing people is keeping the employees in the company. The training of employees to enable them to improve their career development is very important. Good HRM policies ensure that there are clear regulations which show the pay levels for the different positions in an organization. It is important for the staff to know the career path, pay, training and other opportunities that are available to them. Performance management is another important component of HRM. The reason for this is that many employers use it to evaluate career improvement and to determine pay increases.

The secondary role of HRM is the management of the relationships among people in an organization. This includes staff within departments as well as across the whole organization. The relationship between staff and management is an important factor in the success of an organization. It decides how fast an organization will realize their goals.

The focus of HRM is the people within an organization. Regular planning, monitoring and evaluation are important for the success of HRM. Successful management ensures that all employees know their role, career development and also feel part of an organization.

But actually this question is not as simple as it seems. There are thousands of different kinds of fishes, and they vary a great deal in size and life span. Moreover, it is not easy to find out just how long a fish lives in its natural state. We can find out how old a fish is by studying its scales, but we cannot say how much more time it would live if we had not caught it.

We may rear fishes and record their life span but we cannot be sure that this is the length of time they would have lived, had they been left alone.

We may make marking to show how fast the fishes grow so that we can calculate the age of the largest on record, but unless this large fish dies of old age we are still not in a position to know its natural life span.

Unlike human beings, fishes do not stop growing when they reach maturity. They continue to grow as long as they live, although the rate of growth slows down in mature fishes.

People often ask the specialist on fishes regarding its _______.

A.size

B.life span

C.age

D.variety

The specialist is embarrassed by the question because _______.A.he does not know the answer

B.there is no answer to the question

C.it is a silly and simple question for him

D.there is no definite answer to this question

We can know a fish’s age from its ______.A.weight

B.size

C.scales

D.length

Which of the following statements is NOT true？A.Different kinds of fishes have different life spans.

B.It is hard for the specialist to know the length of time a fish lives in its natural state

C.Mature fishes grow more quickly than young ones.

D.The specialist makes marking to know the rate of growth of fishes so that they know the age of the largest ones.

Human beings, unlike fishes, _______.A.stop growing when they reach maturity

B.grow faster after maturing

C.continue to grow as long as they live

D.have a short life span
