Six aspects of the work environment have been found to increase job involvement,

A good answer will include the following key points.
Job involvement, work motivation, and job satisfaction are increased if:
The work feels meaningful and important to employees;
Employees have control over many aspects of their work;
Tasks are varied rather than repetitive;
The company maintains clear and consistent rules;
Employees receive useful feedback about their work, so they know what they have accomplished and what they need to do to improve; and
Employees have many sources of social support, including from colleagues and supervisors.
Work motivation is related not to the amount of money you get, but to how and when you get it.
The strongest motivator, in terms of money, is incentive pay or bonuses.
