Deprive staff, including head of recruitment (6)
I believe the answer is:
starve
'deprive' is the definition.
(starving is a kind of depriving)
'staff including head of recruitment' is the wordplay.
'staff' becomes 'stave' (synonyms).
'including' is an insertion indicator.
'head of recruitment' becomes 'r' (I can't explain this - if you can you should believe this answer much more).
'stave' going around 'r' is 'STARVE'.
Can you help me to learn more?
(Other definitions for starve that I've seen before include "Eat nothing" , "Deprive of food" , "Fail to take in" , "Suffer from food deprivation" , "Deprive of sustenance" .)
