UPSers displays my retro pay. I kept a running spreadsheet and it's exactly what I figured it to be, surprisingly, given that the check for my Preload hours was about $10 off.
Do seasonal helpers (and other seasonal employees) get retro checks, too?
Update of my previous posting (since I cannot edit it at this point):
I just spent the last five minutes double-checking my spreadsheet inputs from my retro pay period. I errored on an entry; both my preload and driver helping hours are 100% accurate.
