Have been on part time graduated return from ML this year, but earned leave last year at full time rate. It's been very hard to take any time off, since all my meetings etc have been on the two days I've been working. I also earn extra TOIL by doing a late shift (compulsory) which will make another 3 days before the end of the year. What this boils down to is I still have 21 days leave to use before the end of the year. 
I'm going back to full time from next Monday, so will officially be entitled to about another 6 days or so. I can carry some over to January, but have a big project launching in the middle of Jan so taking time off will be very hard. I'll be going on ML very shortly thereafter, so will try to use up as much AL as they'll let me before the EDD, but this will probably not amount to much.
SO, do I claim the extra 6 days leave in the full knowledge that I probably won't be able to use it, or do I just leave it and say, I can't take time off anyway so what's the point bothering the HR dept yet again?
And yes, I know I get tons of leave, but do have to work bank holidays if that makes it any less cushy
