Which action is NOT required for a partner to request a leave of absence?

In the context of a leave of absence request for partners, the correct choice highlights that notifying the HR department is not a required action. Instead, the primary steps partners typically undertake involve directly communicating with their immediate supervisor or manager regarding their leave. This makes sense, as the manager plays a critical role in assessing the situation, approving the leave, and ensuring that operational needs are addressed.

Calling MATRIX suggests that there may be an external resource or service that manages leave requests and provides guidance; thus, it is essential for the process. Confirming the last day worked is also a necessary part of tracking the leave accurately. These actions are instrumental in managing leave effectively, ensuring that all parties involved are aware of the partner's status and plans.

Notifying the HR department, while still important, is often considered an administrative step that may not be the immediate responsibility of the partner requesting the leave. Instead, it is typically taken care of as part of the broader management process once the leave has been approved by the manager. This aligns with many organizational protocols where immediate supervisors are the first point of contact in such circumstances.
