Employee hired as Contractor in error

We have persons that have been hired as Contractors instead of Employees. What is the best way to correct this? We have tried 'reversing' the Contractor hire by following the following steps:

Cancel Contractor work relationship

Reverse Termination Pending Worker

Cancel Work Relationship Pending Worker

Run scheduled process Complete the Recruiting Process

Manage Job Offers - Return to Manual Processing

Manage Job Offers - Redraft Job Offer

Edit Offer - Change Worker Type

These steps have proven difficult. Is there a better way? Should we just terminate the Contractor work relationship and hire as an Employee? Looking for advice.
