How to exclude contingent worker in approval hierarchy

Summary:

Hi All,

I have a requirement to exclude Contingent workers in approval workflow hierarchy.

As a below scenario.

User1: Emploee with supervisor is User2

User2: Contingent Worker with supervisor is User3

User3: Employee with supervisor is User4

User4: Contingent Worker with supervisor is User5

User5: Employee

If User1 creates the requisition/invoice the workflow to exclude the Contingent worker (User2) and approval should goto next level User3 and if user3 approves the workflow should bypass the User4(contingent worker) and approval request should goto User5 (employee)
