Traditional union can get you a good job (3,6,3)
I believe the answer is:
old school tie
'a good job' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'traditional union can get you' is the wordplay.
I cannot really understand how this works, but
'traditional' could be 'oldschool' (I've seen this before) and 'oldschool' is found within the answer.
The remaining letters 'tie' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for old school tie that I've seen before include "Symbol of private education" , "Term for group loyalty of those with posh private eduction" , "Emblem of a person's education" , "System of favours between those with a privileged education" , "Upper-class emblem of loyalty" .)
