Staff taking a strike in the cape (7)

I believe the answer is:

matapan

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

'the cape' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I can't see?

'staff taking a strike' is the wordplay.
'staff' becomes 'man' (as in staffing or manning a particular place).
'taking' is an insertion indicator.
'strike' becomes 'tap' (tap can mean to strike or hit).
'a'+'tap'='atap'
'man' enclosing 'atap' is 'MATAPAN'.

'in' is the link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
