I forgot to mention that you must to define a default scope for getting
first all Managers or Workers in each case and a before create filter to set
the role the person you are creating will have or whatever:
#manager.rb
before_create :set_manager_role
default_scope :where => {:role => "manager"}
private
def set_manager_role
self.role = "manager"
end
The same for the worker model
