Cut in staff (4)
I believe the answer is:
crew
I believe this clue is a double definition.
'cut' is the first definition.
(crew cut is a type of haircut)
'staff' is the second definition.
(crew of workers)
'in' acts as a link.
(Other definitions for crew that I've seen before include "This male hair style is closely cropped" , "Ship's men" , "Ship's company - boasted" , "Hands" , "Was exultant" .)
