Remind both parties that they are on the same team

When conflicts occur, it's common to metaphorically "turn away" from the other person. We see the other person through a negative lens, focusing on what's missing, what's wrong, or the other person's flaws. 

Remind the individuals that they are on the same team. Ask them to think about how much they value their position at the company and how important it is for them to work well together. This shift in their thinking brings the bigger picture into play as it reminds them that they are a part of the larger organization.
