Leo perhaps about to go on the dole? (6)

I believe the answer is:

signon

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

'go on the dole?' is the definition.
I know nothing about this answer so I can't judge whether this works.

'leo perhaps about' is the wordplay.
'leo perhaps' becomes 'sign' (leo is a kind of sign).
'about' becomes 'on' (as in a book 'on' a certain topic).
'sign'+'on'='SIGNON'

'to' acts as a link.

Can you help me to learn more?

I've seen this clue in The Irish Times.
