We realize that many employees are assigned to more than one position or location for their company. The conflicts filter will show you a clear indication that an employee is already scheduled elsewhere when you are applying various filters or sorting options.
For example, here I have selected just the "busser" position for my org and enabled conflicts.
You can see that there are shifts shown (in grey) that list where an employee is already scheduled for another position.
This prevents you from spending time switching between views to check for availability as well as the frustration of moving a shift, only to discover that there is a conflict you could not see due to the filters applied.
