Well you said it.

> A Person has a manager. An Identity does not.

My local health service no longer calls people 'patients'. People who 
use the services are called unsurprisingly 'service users'

While I abhor the impersonal overtones of this particular bit management 
speak it makes perfect sense in terms of describing the entity concerned.

In the case you quote surely a manager manages Employees

or

An Employee *has a* Manager
A Manager manages one or more Employees
An Employee has one or more Roles
An Employee has an Identity (or many if you insist)
A Manager *is an* Employee
etc etc

No mention anywhere of the class *Person*

You state

'A Person may have more than one Identities' (sic)

I'd prefer 'An Employee can have one or more Roles/Identities'

A person with multiple identities doesn't really make sense does it?

How do you identify someone with multiple identities???
