Human Factors
We were going to load Aircraft X to ZZZ while loading the mail there was a box that had a Dangerous Goods (DG) sticker on it but there was no paperwork for it. At this time it was decided to be held off and sent back to air freight. The [package] was then rebooked for Aircraft Y to ZZZ and we were told it was ok to load cause we have an agreement with the [US] Post Office. We then notified the Supervisor on Duty in which notified the Manger about the concern they made a phone call and emailed the Regional Freight Manger and was told it was ok to board. We had then notified the pilot which the contacted the DG hotline and was told to hold off aircraft because without paperwork he would not have any ability to react in case of an incident so refused boarding of mail [package]. Also we are unaware of any other DG's being shipped cause of mail items being shipped in sacks.
Air Carrier Ground Personnel reported Dangerous Goods package scheduled to be shipped was refused due to no required Hazmat documents provided.
