In my building if you have a ton of NDA that you think you can’t do, drivers inform the sup who spreads it out to air drivers and ad cuts.
Look at what you have, if you can’t do it then tell somebody. UPS may suck at a lot of things but one thing that is universally encouraged is to speak to managers about problems when it comes to making service. They won’t mind discussing air services because that makes UPS the money and guaranteed that work load will be made to work.
UPS does not fook around when it comes to EAM and NDA. The rest? Well the rest you do when you do.
