OK, one last attempt (still hoping that the suspicion that this discussion might

Agreed, so far.

The operations on secretaries are usually a superset of the operations on employees, 
while the operations on unsigned integers are a subset of the operations on signed 
integers. 

Inheritance is only applicable in the former case. The flaw in the latter scenario
is similar to adding operations specific to secretaries, trainees or managers to 
the interface of 'employee'.
