Permission Groups for Contingent Workers in the guide says that we should setup a permission group with 0 = employees and 1 = contingent workers, however when we try and search for '1' to assign to the contingent workers excluding group, it does not appear.
Employee Central: Contingent Workforce
This is because there are currently no users in the instance with the isContingentWorker field set to 1. You can go ahead with the rest of the configuration, skipping this step for now.
You can check back once you have at least one contingent worker in the instance. Anyways, this step is not mandatory for setting up CWM and is only required when you want to have some permissions specific to CWs.
