Then you should use it.
Especially if your company "caps" your vacation accruals like mine does.
You accumulate a certain number of hours and then the accrual automatically stops, even though you are still working.
I still need to look into the sitcheeayshun with regard to capping of the accrual. The "new" parent company doesn't let vac annual accrual go beyond 4 weeks/yr. Well... I was already *at* five weeks/yr when the buyout happened oh-so-many years ago. At least *that* part got grandfathered in. Seems there is a new rule that caps total accrual at two years' worth.
But now I find that I've got ten weeks on the books, and I'm starting to lose new accrual if I don't take some.
So... I'm taking tomorrow off... to... think about it...
