Work with solicitor or choose to depart? (3,3)

Ross

I believe the answer is:

opt out

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

'choose to depart?' is the definition.
I can't judge whether this definition defines the answer.

'work with solicitor' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'with' means one lot of letters go next to another.
'solicitor' becomes 'tout' (someone who solicits business).
'op'+'tout'='OPT-OUT'

'or' acts as a link.

Can you help me to learn more?

(Other definitions for opt out that I've seen before include "Choose not to participate" , "Decline to participate" , "'Choose not to take part (3,3)'" , "Choose not to do something" , "Choose to be excluded" .)
