How to set up leaves from work?

To set up leaves from work you need to follow this path: Configuration >> Calendars >> TIme off >> Create leave from work >> Next

Here you'll find the following configuration options:

• Request for approval. By activating this option, it’ll be mandatory for time off requests to be approved by the employees assigned to this task. 
• Set as private time off. By activating this option, this time off will automatically require approval, so the first option will be enabled as well. Specific time off are those that cannot be validated by any holiday validator, but can only be accepted by those employees who have been configured as time off administrators.
• Allow for attachment of supporting documents. When employees request this time off, they have the option to attach one or multiple documents. Users with Time plans don't have access to the document management tool, so they won't be able to see these documents when they are uploaded to the system.
• Block time off according to ranges. Periods can be set up when employees CANNOT request this time off.

Before clicking on Create you can see a summary of the configuration you have created on the right-hand side.
