No expert on Django, and it's hard to tell what your GOAL is from this
description, but you might want I'd write something like this:
class Employee(models.Model):
name = models.CharField(...)
class Manager(Employee):
manager_stuff...
class Worker(Employee):
worker_stuff...
manager = models.ForeignKey(Manager,related_name="subordinates",
blank=True, null=True)
class WorkerTypeA(Worker):
workera_stuff..
class WorkerTypeB(Worker):
workerb_stuff...
class ManagerB(Manager):
a_person = ForeignKey(
more_manager_b_stuff...
Again, depending on what your goal is, you might not even need that
a_person field now, since Workers can have managers, and managers can
have subordinates.
