UPS reveals secrets behind how you get your gift to grandma

This holiday season, UPS expects to send more than 585 million packages around the world. That's a lot of boxes and getting your last minute gift to your grandma in Alaska is no easy feat.

Here are some inside secrets on how UPS makes the magic happen:

First, they watch every move their employees make. UPS trucks track drivers' routes, how hard they're braking and even whether or not their seat belts are buckled. Most drivers have between 150 and 200 packages to deliver daily and the handheld device they have you sign for your deliveries make sure they're moving.

In May, Jack Levis, director of process management for UPS told NPR, "one minute of idle per driver per day is worth $500,000 of fuel at the end of the year."

Another secret of the brown box brigade? They can't turn left. Yep, UPS drivers and Derek Zoolander
have a lot in common.

Around 2001, UPS started asking drivers to cut down on left turns to reduce time spent in traffic. According to UPS, "even if this meant traveling a greater distance, results showed that more packages could be delivered in less time with reduced emissions by driving in a series of right-hand loops. It helped the bottom line, met consumer demands and increased safety."

All drivers have to graduate from a class called "Intergrad" where they carry packages packed with cinder blocks, learn to start their trucks with one hand while buckling up with the other, and run through a practice delivery route.

But their hard work is worth it - safe and efficient drivers are rewarded with gifts including bikes and grills. Those who work for 25 years without an accident are inducted into the UPS "Circle of Honor" and are given a sweet bomber jacket.
