These relationships are usually not as deep or trusting as personal ones making resolving disputes more difficult and challenging.

Interestingly, most workplace conflict is totally unnecessary because they are usually the result of simple misunderstandings, miscommunications or small differences that could be easily resolved if the parties truly knew each other's motivations.
