The minority in safe work? (3)
I believe the answer is:
few
'the minority' is the definition.
(I've seen this in another clue)
'in safe work?' is the wordplay.
'in' indicates the answer is hidden within the clue.
'FEW' is hidden in the letters of 'safe work'.
(Other definitions for few that I've seen before include "Considerable number, ironically" , "Relatively small number" , "Not many, just a handful" , "Indefinite but small number" , "Indefinite small amount" .)
