			Simple derivation of work function of metals based on the bulk-plasmon contribution is discussed  here  in  a  form  of  a  comment  to  previously  published  work.  We  show  that  such  a  derivation  is  neither  the fi first  of  its  kind,  nor  it  is  in  agreement  with  experimental  data.  Incidentally,  the  physical  foundations of the proposed derivation appear  to  be  flawed.
