Have you informed the pension dept of your intention to retire? When are you due to retire?
It is advisable to inform your manager and the pension dept at least 8 months prior to your redundancy date, giving them plenty of time to enable everybody to arrange your drop down in hours.
Your manager should have explained to you the drop in hours, which is one fifth of your contracted hours, and arranged, by mutual agreement, as to what shift/ hours you drop. This takes effect for your remaining 6 months to your retirement date.
So if your having a day dropped from your shift, you are still paid for it, and it is still classed as your working week. Therefore you still get the same allowance regarding holidays, bank holidays etc.. It is not covered by your allowance, and you don't have to use up any entitlement to cover it...think off it as T/L in advance.
You can use any remaining holidays, or b/h entitlement to finish earlier, if you still have some outstanding, nearer the date, again mutually agreed.
How long have you worked for Tesco's?? As some long serving colleagues will have accrued frozen pay, from when they started, based on the contracted hours you did then, not now. So if you qualify, this should also be paid on retirement.
If your age plus years of service add up to 80 years or more, you keep your discount card.
