Well, carriers really have no say as well as no business changing color code days on mail. The system is not referred to as the chameleon color system where we just go slinging a different color code tag on mail just to make it APPEAR to be current. If the mail has a blue tag on it, MONDAY is the latest it can go. It CAN GO SOONER. Don't be afraid to take it on SATURDAY. Like you said
@Morty , when everything goes every day, you do not run into these issues. Also, any mail curtailed must be reported by management as delayed mail. I have seen a couple PMs walked out and several supervisors get into some serious trouble over the years for NOT reporting delayed mail.
