Stay professional and keep emotions out of the conflict
As Management Issues states, the most important thing is not to take things personally, remain professional, and avoid unnecessary emotional involvement. Show the subordinate that even in the face of personal tension, it is still possible to maintain a working relationship.
Find the root cause of the problem
Recognise the core issue. As mentioned above, there may be many causes behind a mutual – or even one-sided – dislike. In order to resolve the situation effectively, you first need to identify what problem you are actually dealing with.
Talk to the subordinate calmly and in private
Do not address the issue in public. Instead, have a calm and private conversation with the employee in question. Address the topic openly using a positive approach, and discuss the matter transparently.
Lead by example and take the first conciliatory step
Regardless of who started the conflict or whether you believe the subordinate’s behaviour is fair, try to take the first step towards resolution. Show that a professional and healthy relationship with the subordinate is more important to you than being right. There is a fairly good chance that if you express a sincere desire to resolve the situation positively, the subordinate will also be willing to seek reconciliation.
