Read the following passage and answer the following question:
There has been pressure for increasing productivity and higher earning for a worker in the industry. There are several ways of increasing employees earning. Employee earning can be increased by raising the selling employees earning. Employee earnings can be increased by raising the selling prices of the firm’s products and services, reducing profits or cost of raw materials or augmenting labour productivity. However, an increasing employee earning by means other than increased labour productivity jeopardizes the firm’s competitive strength in the market. Higher prices usually mean fewer customers, reduced profit means less capital investment and low cast material mean poor product quality. But increasing labour productivity by enhancing skills and motivation creates an almost unlimited resource.
