In Workday staffing, position restrictions define which values are allowed when a worker is hired into a position. In this scenario, Worker Type is restricted to Employee, but Worker Subtype is blank. A blank optional restriction does not mean the manager cannot select a value; it means the value is not restricted by that specific field. Because Worker Type is restricted to Employee, the available subtypes must be valid subtypes under the Employee worker type. The manager can therefore select any Worker Subtype that belongs to Employee, such as Regular or another configured employee subtype. The answer is not Employee because Employee is a worker type, not a worker subtype. Contingent Worker is incorrect because it is a different worker type and is excluded by the Employee restriction. Any subtype of the Contingent Worker worker type is also incorrect because contingent worker subtypes are not valid when the position is restricted to Employee. The restriction framework narrows subtype choices through the selected worker type. Therefore, any subtype of the Employee Worker Type is correct.
