# Split unavailability

### What is the "Split Unavailability" feature for?

This feature allows you to insert a session in the middle of a staff unavailability period. This automatically splits the unavailability into two, before and after the added session.

It is useful when, even if a staff member is noted as unavailable (for example, for a whole day), they exceptionally agree to provide a session at a specific time.

### How to use the "Split Unavailability" feature?

#### Detailed steps

1. **Access the schedule**:
   * From the **Graphic Planning**.
2. **Identify unavailable staff**:
   * A gray area appears on their schedule at the time they are unavailable.
3. **Drag a session onto this gray area**:
   * Create a new session or move an existing one within the downtime period.
4. **Confirmation window**:
   * Yoplanning displays an alert indicating that the staff is unavailable.
   * You are offered to **split the unavailability** to insert the session.
5. **Validate the action**:
   * By confirming, the unavailability is automatically split:
     * There is still unavailability before the session.
     * Another one is created after the session.
   * The session is successfully assigned to the selected staff.

### Best practices

* Use this function only if you have received confirmation from the staff.
* Add a comment to the session to keep track of this exception.
* Check that the remaining unavailability does not cover other slots that the staff may have accepted.

### In summary

The "Split Unavailability" feature is a smart, automatic tool in Yoplanning for managing exceptional cases. It facilitates organization while ensuring data consistency across the schedule. This feature can only be used when dragging and dropping on the schedule.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.yoplanning.support/en/yoplanning-academy/yoplanning-au-quotidien/planning-et-indisponibilites-avec-yoplanning/definir-une-indisponibilite-pour-un-membre-de-lequipe/scinder-les-indisponibilites.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
