Drink concluding report on professional barrier (5,7)
I believe the answer is:
glass ceiling
'drink concluding report on professional barrier' is the definition.
I can't judge whether this defines the answer.
'drink concluding report on' is the wordplay.
'drink' becomes 'glass' (a glass of something).
'concluding report on' becomes 'ceiling' (I am not sure about this - if you are sure you should believe this answer much more).
'glass'+'ceiling'='GLASS CEILING'
Can you help me to learn more?
(Other definitions for glass ceiling that I've seen before include "Barrier preventing promotion, due to prejudice etc" , "Unacknowledged barrier to career advancement" , "Artificial bar to promotion" , "Discriminatory barrier to promotion" , "Unseen barrier to women's advancement" .)
