I have insufficient karma to edit another post with the exact same question so I will create a new one.
In Human Resources, a manager should only see their direct employees i.e.
Manager 1 -> Employee 1 and Employee 2 Manager 2 -> Employee 3 and Employee 4 etc
Is this at all possible? A use case could be an employee requests leave and their direct supervisor is emailed and can approve this request. No other employee can see the request or approve.
The duplicate request is http://help.openerp.com/question/38630/rule-in-human-resource-view-employee/ but it is a mess and is likely to never get any answers unless edited.
