Help to recover my start date

[Wally]

Hi, I need some help, I lost my start date when I got rehired and I started working with 5 more people none of them lost who I gotta speak with?

And now a Wallation™:

Greeting fellow forum members,

I am requesting assistance in regards to my current company start date. I was employed at UPS, left my position for other opportunities, then graciously, was rehired by UPS. My start date is incorrectly listed as the date of my rehire, not the previous date. My question is: who must I speak with to rectify this egregious error?
