No employee released weapon, right? (10)

I believe the answer is:

freelancer

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

'no employee released weapon right?' is the definition.
I can't judge whether this definition defines the answer.

'released weapon right?' is the wordplay.
'released' becomes 'free' (similar in meaning).
'weapon' becomes 'lance' (lance is a kind of weapon).
'right?' becomes 'r' (common abbreviation).
'free'+'lance'+'r'='FREELANCER'

Can you help me to learn more?

(Other definitions for freelancer that I've seen before include "Self-employed person" , "One temporarily hired" , "Independent worker" .)

I've seen this clue in The Daily Express.
