Time to question staff about flipping tough boss (10)
I believe the answer is:
taskmaster
'tough boss' is the definition.
(I've seen this in another clue)
'time to question staff about' is the wordplay.
'time' becomes 't' (abbreviation).
'to question' becomes 'ask' (asking a question).
'staff about' becomes 'master' (I am not sure about this - if you are sure you should believe this answer much more).
't'+'ask'+'master'='TASKMASTER'
'flipping' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for taskmaster that I've seen before include "Supervisor" , "One supervising" , "One proverbially hard job given to" , "difficult employer" , "slave-driver" .)
