OMS is literally the best PT supe job UPS has to offer, except maybe HR
depending on whether you work AM, mid-day, or PM, your responsibilities can be vastly different
AM OMS basically distributes call-tags and driver followups, controls high-values, and then does handles the customer complaints that came in over the night. very stressful till the drivers roll out, then it dies down quite a bit.
mid-day OMS is all about hourly reports to IE, a large amount of customer complaints, and some assisting the on-car supes with meetpoints
PM OMS, my job, handles some customer complaints, a lot of will-call requests, all of the timecards, the DIAD's, the recap-report of the day, getting all the drivers in before the air-trailer rolls out, and then picking up the pieces for whatever was screwed up during the day
the AM and mid-day have the best hours, and you will work 5.5 every day, but if you're the PM OMS, you're done when your work is done and all the drivers are in, which hangs on how good you are at your job. The only time i actually work 5.5 hours a day are when i stay late to clean the DIAD's periodically.
Also, if you're the PM OMS, after 7:30pm, you are usually the de-facto Center Manager for whoever is still out
i say take the job, but if you can't handle making big decisions, fast, on your own, stay away from PM OMS..
Edit: you'll make about 20K a year for 27.5 hours a week
if you want to advance by meeting people, take the mid-day or maybe AM shift.
if you want to become really, really good at anything UPS can throw at you, take the PM shift.
