'Give Them A High Five': USPS Enters Busiest Week Of The Year

DENVER (CBS4) - The United State Postal Service is entering its busiest week of the year. Employees are hard at work sorting the parcels overnight to have them ready for carriers the next morning.

As busy as they are, it might be the favorite time of year for some.

"It's the one time of the year we really get to deliver that joy and have that reciprocal so if you see one of those employees out there, give them a thumbs up, give them a high five, a smile. They need it they're working hard, but they're working hard for you," said David Rupert, a USPS spokesman.
