But you can also spend it preparing to hit the ground running next year, by giving your email inbox the TLC it deserves - so you don't get that sinking feeling when you get back to the office.
Tired of getting the warning about your inbox almost being full? Put your feet up, put the telly on, get out your laptop and go as far back as it will take you - then delete.

If you know certain senders or subject lines will be associated with specific projects, set rules so they are automatically labelled.
5. Smash those templates
Do you find yourself writing the same email over and over as people come to you with the same enquiry? Spend half an hour creating templates of responses, which you can customise with a name and a short message at the end.
6. Filters to rule them all
Sharon from HR may bring in cake every day, but her generous emails - and the lengthy "banter" chains that ensue - are clogging up your inbox. Create rules or filters which automatically delete or archive emails from certain senders, or with certain words in the subject line, to avoid those pointless chains. And to be blissfully unaware of office cake as you enter January...
