Idiosyncratic deals must be managed effectively in order to make sure they can exist without disrupting others' sense of fairness.

Idiosyncratic deals are individualized agreements between employees and their managers that may not conform to standard organizational policies or practices. However, these deals can cause other employees to perceive favoritism or inequity if not managed effectively. Therefore, it is important to ensure that these deals do not disrupt others' sense of fairness in the organization.
