U.S. senators grilled the head of the United States Postal Service Tuesday. They wanted answers regarding lengthy delays being experienced across the country, particularly in Georgia."Atlanta is particularly problematic where we saw service plummet. In-bound first class mail has dropped to only 36% on time," said Sen. Gary Peters (D - MI)DeJoy blamed the delays on what he said is an overdue USPS restructuring plan. The plan looks to make USPS more efficient and in a better position to compete with FedEx and UPS."We have to allow time to transition," DeJoy said Tuesday.The plan involves consolidating local mail distribution offices into large, regional hubs. The USPS has opened one of these centers in Atlanta. While the facility has experienced significant delays, DeJoy insisted Tuesday that things are looking up."Now that the organization is engaged, I am confident. I see the whole team getting better, understanding the transition we need to make, committing to the transition we need to make," he said.Georgia's U.S. Senator Jon Ossoff told the Postmaster General he is still not happy about what's been unfolding at the distribution center in Georgia."I've got constituents with prescriptions not being delivered. I've got constituents who cant pay their rent and their mortgages. I have businesses who can't ship products or receive supplies," he said.DeJoy said they are working to address the delays."We have engaged over 50 different management executives on sight. We are finishing up our staffing at the main three locations. We're looking at our truck schedules, we're revamping our truck schedules. We are stabilizing the operation in terms of machinery we have deployed there. We are working better. We have special teams on sight working on our docks, working on the rest of the transportation aspects of this that are causing a significant amount of problems. The two plants where we did a lot of transfers, within the next ten days, we should have them fully staffed. We had some issues with those transfers. The team is working very hard and I can assure you in the long run, you will have the best service," DeJoy said.Ossoff was not satisfied with DeJoy's answer."The long run is too long. You have weeks, not months, to fix this. If you don't fix it, 36% on-time delivery, I don't think you're fit for this job," Ossoff said.Several of the senators who spoke during Tuesday's hearing reminded DeJoy of the importance of getting these issues resolved ahead of the November election.
