Drunk is cross with last boss employed by the barbers (8)
I believe the answer is:
scissors
'employed by the barbers' is the definition.
I can't judge whether this definition defines the answer.
'drunk is cross with last boss' is the wordplay.
'drunk' indicates an anagram.
'with' means one lot of letters goes inside another.
'last' indicates one should take the final letters.
The last letter of 'boss' is 's'.
'is'+'cross'='iscross'
'iscross' is an anagram of 'scisors'.
'scisors' placed around 's' is 'SCISSORS'.
Can you help me to learn more?
(Other definitions for scissors that I've seen before include "Paper/cloth cutters" , "Wrestling hold" , "Small shears" , "Cutting device with two long blades" , "Cutting tool" .)
