The Shoemaker is this person in the workplace whose work ends up
getting done by his line manager and/or by the firm's client. They can't sack him cos he's too cute and has been with
the company from day one as well has having loads on them. People are left wondering how the work is getting magically done, and refer to those who are doing it as being elves. As in
the children story " The elves and the shoemaker".
