'extra wages' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'remove it wrongly to spend' is the wordplay.
'wrongly' is an anagram indicator.
'to spend' becomes 'pay' (I can't justify this - if you can you should believe this answer much more).
'remove'+'it'='removeit'
'removeit' with letters rearranged gives 'overtime'.
'overtime'+'pay'='OVERTIME PAY'

'as' acts as a link.
