forgoing

'doing without' is the definition.
The definition and answer can be both to do with ownership as well as being present participle verbs.
Perhaps they are linked in a way I don't understand?

'because working' is the wordplay.
'because' becomes 'for' (I've seen this in another clue).
'working' becomes 'going' (working can mean going or activated).
'for'+'going'='FORGOING'

Can you help me to learn more?

(Another definition for forgoing that I've seen is " Giving up (something desirable)".)

I've seen this clue in The Globe and Mail.
