I work at my particular hub that delivers to my house. HOLD FOR PICKUP tells the system to not route it to my normal truck, and exception the package out when it hits the scanners. From there, meander over to the customer counter and pick up my package after the shift. I get my goods just like everybody else does. UPS takes package security seriously, and I play by the rules. I won't do anything on the job that even has the appearance of impropriety.
If it gets on a truck, it's not coming off. That package goes out for delivery.
This might be a dumb question, but is it safe to change delivery to pickup at the UPS hub when the order status is still "Ready for UPS"?
