True or False: Workers can be assigned to multiple supervisory organizations simultaneously.

In Workday, workers can only be assigned to one supervisory organization at a time. This structure is designed to maintain clear reporting lines and accountability within the organization. The supervisory organization serves as a means to manage and oversee workers directly, ensuring that there's a distinct hierarchy that can be effectively utilized for performance management, compensation planning, and other managerial functions.

Assigning a worker to multiple supervisory organizations simultaneously would complicate reporting relationships and managerial oversight, making it difficult to establish clear lines of authority and responsibility. As a result, workers are restricted to a single supervisory organization to streamline these processes and maintain organization integrity.

Other options suggest varying levels of flexibility regarding supervisory assignments, but the foundational principle of a clear and singular reporting structure is what drives the necessity for a worker's singular assignment to a supervisory organization.
