Grievances may occur due to a number of reasons:

2. Work environment:

It may be undesirable or unsatisfactory conditions of work. For example, light, space, heat, or poor physical conditions of workplace, defective tools and equipment, poor quality of material, unfair rules, and lack of recognition.

3. Supervision:

It may be objections to the general methods of supervision related to the attitudes of the supervisor towards the employee such as perceived notions of bias, favoritism, nepotism, caste affiliations and regional feelings.

4. Organizational change:

Any change in the organizational policies can result in grievances. For example, the implementation of revised company policies or new working practices.

5. Employee relations:

Employees are unable to adjust with their colleagues, suffer from feelings of neglect and victimization and become an object of ridicule and humiliation, or other inter- employee disputes.

6. Miscellaneous:

These may be issues relating to certain violations in respect of promotions, safety methods, transfer, disciplinary rules, fines, granting leaves, medical facilities, etc.
