Paul Glover identifies six typical sources of conflict in the workplace: skill deficiency, different interests, stress, organizational deficiency, lack of resources, and personality clashes. He claims that 70% of workers report that stress is the biggest cause of conflicts, as employees feel pressure to be productive while worried about job security, and sometimes take out their stress through conflicts. Glover also argues that conflicts are an inevitable part of life and work, and that managers should recognize the sources and learn to handle conflicts constructively by facilitating respectful communication between opposing sides.
