Pole worker (3)
I believe the answer is:
elf
'pole worker' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for elf that I've seen before include "Pixie (able to cobble?)" , "Mischievous creature" , "A small sprite with magic powers" , "tiny little chap" , "Dwarf" .)
