Half of flipping idle workers getting stick (7)
I believe the answer is:
distaff
'half' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'flipping idle workers getting stick' is the wordplay.
'flipping' is a reversal indicator.
'idle workers getting' becomes 'id' (I can't explain this - if you can you should believe this answer much more).
'stick' becomes 'staff' (staff is a kind of stick).
'id' reversed gives 'di'.
'di'+'staff'='DISTAFF'
'of' is the link.
(Other definitions for distaff that I've seen before include "Rod for flax - not the spear side" , "Female - rod on which wool or flax is wound before spinning" , "Stick holding wood, in spinning" , "(referring to the women)" , "concerning women" .)
