Foreman (6)
I believe the answer is:
gaffer
'foreman' is the definition.
(I know that foreman can be written as gaffer)
This is all the clue.
(Other definitions for gaffer that I've seen before include "Informal boss or foreman" , "one prone to blunder socially?" , "man in charge" , "Boss, overseer" , "Supervisor; chief electrician" .)
