Does anyone know of a way to implement permissions within a SharePoint list so that items are only visible to the person who created it (or potentially who the list item is "assigned to", as in like a Task) and also their manager (and their managers and so on). So any person can see all items that are either their own or belong to a subordinate?
I hope that makes sense? Any realistic way of doing this?
I'm using SharePoint Server 2010.
