Common Causes of Work Related Conflicts
With these different types of conflicts in mind, we can identify three common causes of work-related conflicts; work-family conflicts, work-employee conflicts, and employee-employee conflicts.
1. Work-Family conflicts. The link between work and family. Conflicts tend to arise when employees are overworked and are asked to work longer hours. This has an effect not only on the worker, but on the family too. Spending more time at work and less time at home with family has stirred up several conflicts.
According to U.S. reports, "90 percent of American mothers and 95 percent of American fathers report work-family conflict." 
2. Work-Employee conflicts. The link between the employer and the worker. Conflicts tend to arise from opposing ideas, decisions, and actions at the work place.
Many work related conflicts are caused by employees being told what to do, how to perform, to work longer and harder, accept more responsibilities, as well as to meet certain demands.
A situation where there is a possibility of conflict between work and employee is during times of personnel evaluation. Periodically, employers will need to evaluate their workers to decide on promotions, raises, or even retention. A conflict could arise from a negative evaluation, when an employee does not receive a good progress report caused by their character, behavior, personality, or work conduct or performance. Possible conflicts from a negative report could include being put on probation or fired.
Work-employee conflicts tend to occur when a worker has a tendency to being late, lacking motivation, performance, make continuous errors on the job, or disrespecting others (as co-workers, customers, management, or the boss).
3. Employee-Employee conflicts. The link between employees. Conflicts between employees are personal, but they have an effect on others in the workplace as well. These conflicts happen when employees do not get along and are not able to work or confront each other. Conflicts between co-workers are unpleasant to see and are distracting to others in the workplace. They tend to lower workplace morale and productivity; they can affect workers' chance for promotion or worse, the retention of their job.
