Section 53-A. Department heads

The town board shall appoint the head of any
  department  of  the  government  of  the  town established or created in
  accordance with the provisions of this article.  Such  department  heads
  shall  be  principal  executive officers of their respective departments
  and their offices shall be in the unclassified service, and unless their
  titles are otherwise designated by the town board, they shall  be  known
  as  directors.  Salaries  of department heads shall be determined in the
  same manner as is provided in the annual  budget  for  the  salaries  of
  other  town  officers,  provided,  however,  that  where the duties of a
  department head are increased, altered or diminished by local law and to
  the extent funds are available therefor, appropriate adjustment  may  be
  made in such local law in the salary of such department head.
