Semantics of "Direct Reports"?

What I know about the “Direct Reports” relationship, if I’m not mistaken: it’s a one-to-many relationship linking two Contacts.

This means that a certain contact can have many people who are his “direct reports”, but each person can only report directly to a single manager.

What I don’t know, and would like to ask: are there any other less apparent semantics taking effect, or does SuiteCRM simply record the relationship, display it, and do nothing more about it?

Things like: the manager being able to access certain records of his direct reports; or notifications to the manager of things happening to the direct reports; or any change in the logic of record assignment, etc.

Thanks in advance for any insights on this.
