Why on earth would anyone expect a straight answer to a question like this on this site? This is such a highly technical question that the likelihood of anyone on this forum being able to give a reliable answer is close to nil. Call the UPS corporate office and ask to speak to payroll. Google says the number is: 404-828-6000. Another member posted this number on a other thread about a similar issue. I think it's for HR: 1-855-877-4772. No idea is it's a good number or not.
