Welcome to Brown Cafe.
You are what is called paperless direct, which means you have direct deposit and do not receive a paper pay stub. Your sup is right in that you can view your paystub online.
Go to upsers, click on the My Life and Career header, scroll down to My Money, click on that, scroll down and click on View My Paycheck, click on the blue View My Paycheck link and you should be all set from there.
You can opt for a paper statement but you will see that you really don't need one as you can print right from upsers. The only stub that you really need is your end of year pay stub which you can use to do your taxes. On that note, your W-2 should be available (also on upsers) about two weeks before you get in the mail.
