Pack up work for the rest of the year (2,2,7)

'year' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'pack up work for the rest of' is the wordplay.
I cannot really see how this works, but
'work' could be 'go' (synonyms) and 'go' is found within the answer.
'rest' could be 'holiday' (I've seen this before) and 'holiday' is found within the answer.
'of' could be 'o' and 'o' is located in the answer.
A single letter 'n' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'the' acts as a link.

Can you help me to learn more?
