Natural HR allows you to disable the ability for your employees to edit or delete their time off bookings.

To do this navigate to

Administration -> Company -> Settings -> Time off settings (Global)

In the 'Self service' section you will see two options available 'Allow employees to edit time off' and 'Allow employees to delete time off' shown below:

If either of these options are set to 'Yes' then your employees will be able to edit and/or delete their time off requests by navigating into:

Self-Service -> My requests -> Time Off

On this page, In addition to the View action, the employee will also see the 'Edit' and 'Delete' actions in the 'Actions' column.

If however, either of these options are set to no then the corresponding action will not be available to employees. It is important to note that Approver, Manager, HR and Admin level users will have the ability to edit and delete these instances on behalf of the user if required, regardless of both of these settings.
