We thought not, but did you realise that that's exactly what you may be doing by not using all of your holiday allowance? Last year the average British worker lost out on 4.4 days holiday - the equivalent of handing back ?378 of their salary. And with mere weeks to go until the end of the holiday year the holiday blackhole is predicted to be even greater this year. The average worker still has 5.8 days unused holiday to enjoy, which if you're one of the high earners could be the equivalent of as much as ?1,368, according to Expedia. We Christmas nearly upon us we suggest you book off a shopping day or two.
