Create an 'on-leave' role:

It would be useful to be able to give a faculty member who is going on maternity leave or extended sick leave less access to their account, but not have to remove roles and change a bunch of settings that would then have to be -added at a later date. 

A person on leave would need access to a bit more than the general public (for eg. access to the calendar, resource page) but should have the same access as an employee. 

It would be important to make sure a person with this role could still access their parent persona.
