Individual non-member of a union (6,6)

I believe the answer is:

single person

I'm a little stuck... Click here to teach me more about this clue!

'a union' is the definition.
I know nothing about this answer so I can't tell whether this works.

'individual non-member' is the wordplay.
'individual' becomes 'single'.
'non member' becomes 'person' (I can't explain this - if you can you should give a lot more credence to this answer).
'single'+'person'='SINGLE PERSON'

'of' acts as a link.

Can you help me to learn more?
