Why are we delaying and destroying secondary mail in NDCs? Recirculation counts on the PSMs has been reduced to 5 (approx. 13 minutes) from 13 (approx. 40 minutes). If no clerks are working the slides in one aisle, and a slide is full, then the mail goes to missent, and has to be reinducted through the whole system. There was a much better chance to get mail out in a timely manner before, and in one piece! Now we send it back through all the conveyors, and the dreaded "Shredulator" (SSIU) to keep rewrap clerks busy!
