Agendrix has a shift conflict detector that will indicate where you have possible conflicts needing to be addressed.
A shift conflict is usually generated when an employee is scheduled when she has a time-off, an unavailability or already has a shift. The detector will allow you to easily solve the conflicts while creating the schedule.
By clicking on "Conflict detected", Agendrix will filter out all employees except those with conflicts, allowing you to manage the issue rapidly.
