Employers should attempt to ‘mend fences’ as a first option before things get out of hand.
Act immediately as conflicts don’t general go away by themselves.
Meet with people involved in the conflict separately to get a clear understanding of the issues before you try to intervene.
Focus on what the people involved need and what’s important to them, not on trying to judge who is right or wrong.
Decide whether to mediate or to call in others to help.
