At the Oakland United States Postal Service Processing and Distribution Center workers have been celebrating Christmas every day since December 1st. Different units within the processing plant hold potlucks during their breaks, so they have a chance to celebrate and share food with each other. The facility feels like it’s Christmas time throughout the year, because of the number of mail that whirs through the system.

“Christmas for us, is basically every day,” said senior manager Nancy Canales-Nelson. The sheer volume of mail coming in and being processed is what makes each day feel like Christmas time.

Unlike a typical post office, this facility runs 24/7. Over a thousand employees process packages and letters every day of the year.

In December, the facility typically processes hundreds of thousands of parcels every day with three loud, industrial size processing machines on each floor. Bay Area Communications Specialist Kristina Uppal attributes the craze to the continuous rise of online shopping and early Black Friday sales. Three shifts per day of USPS workers keep things running, and ensure presents arrive in time for Christmas.

“We connect every piece to every door,” Uppal said. “We definitely give Santa a little extra lift.”
