Answer:

Hire temporary employees to work on specific projects.

Explanation:

Human resource management is the process by which a business effectively manages its manpower needs to meet its organisational goals at a reduced cost to the business.

It involves the various strategies used to hire employees to meet business needs in a cost-effective way.

The construction division has a highly seasonal workload, with fewer projects in the winter than in the summer. Also, different expertise is needed for different kinds of buildings. So hiring a permanent workforce is counterproductive as they will be paid when there is no work to be done. The best strategy is to hire temporary workers.

kozerog [31]

Answer:

Option (d) is correct.

Explanation:

If there is an improvement in the technology then as a result the producers will be able to produce more quantity of automobiles with the same level of resources. This will increase the supply of automobiles and shift the supply curve rightwards.

At the same time, the economy is experiencing a recession. This will reduce the income of the consumers and hence, the demand for automobiles also decreases. This will lead to shift the demand curve leftwards.

As a result of these shifts in the demand and supply curve, the equilibrium price will fall and the impact on equilibrium quantity is indeterminate because it will be dependent upon the magnitude of the shift of demand and supply curve.
