I actually coulda used this info. So glad someone gave a legitimate response right away instead of the usual crying about the search function and X number of threads.
It's also something that should be explained on the check itself with a code key. But that's too easy for UPS. FYI, we also had to negotiate that this info even to be listed at all. In the old days (maybe 2 contacts back) you had to ask your Sup to look it up.
The h and d indicate hours and days. You have them misaligned in your post. So it's vacation hours, option days, option week hours, and sick hours. Holiday is not part of the list there.
