In this case, I would have been better off to have set my termination date further in the future than I did, and take the holidays. Then, they would have been "basic" salary days and I would have gotten the pension contribution on them. So, if I finish work on the 1st May with 10 days holidays left outstanding I am renumerated x. If I finish work on the 15th May, having taken 10 days holidays, I am renumerated y. This doesn't make sense to me, maybe someone else has an opinion!
