True. Some people like to spend time without any activity. They may be lazy or they may not be having an interest in doing that work. Such people try to spend time gossiping with the other employees. Mainly we used to see this in some shop floor workers in our industry. They used to complete the work and sit freely. The turn our of work was very less. Then we decided the minimum production levels in each shift and made it compulsory that minimum production (norm) should be there in every shift. This has become a part of the wage agreement. If they produce more than the norm, they will get production incentive and if the production is less than the norm., wages will be paid proportionately. Then onwards the production levels increased and people started earning incentives.
In higher cader, if an employee is not active and not performing in the desired levels, he may lose the job also. This will happen in any private industry. So generally, people will perform to the required level.
