'holiday worker lacking occupation' is the definition.
I can't judge whether this definition defines the answer.

'holiday worker' is the wordplay.
'holiday' becomes 'vac' (abbreviation for vacation).
'worker' becomes 'ant' (worker is a type of ant).
'vac'+'ant'='VACANT'

Can you help me to learn more?
