U.S. Postal Service (USPS) workers will no longer deliver UPS SurePost packages. Here's how fast you could get your deliveries.

Martin Luther King Jr. Day is a federal holiday, but some shipping and delivery services may still be operational. Here's what we know.

"Millions of packages moved away from SurePost and the United States Postal Service and returned to UPS package cars this month, now being sorted and delivered by hardworking UPS Teamsters." the social media post reads.

The United States Postal Service and FedEx say the recent weather is behind delays in folks getting their mail. Customers of both the USPS and FedEx reached out to Nexstar’s WOWK 13 News with concerns that they hadn’t been receiving their mail.

While USPS mail and deliveries will be delayed, UPS and FedEx pickup and delivery services will continue as usual. Generally, UPS and FedEx office locations remain open as well. Business hours vary by location.

While a majority of financial institutions, retailers and schools will be operating as usual on Thursday, Jan. 9, the U.S. Postal Service and all its branches will be closed, according to the USPS.

Wells Fargo says the USPS continues to prioritize yield improvements due to its financial challenges. Every USPS product has shown an increase in revenue per piece (RPP), ranging from 2% to 11% year-over-year, signaling a need for ongoing price adjustments.

The agency said the offering will reach about 87% of the U.S. daily by sending packages to its last-mile delivery units overnight.

The one-day delivery option is designed for businesses with minimum daily shipping volumes that can meet defined cutoff windows.

Martin Luther King Jr. Day is on Monday, Jan. 20, this year. The holiday coincides with Inauguration Day and while Inauguration Day isn’t a holiday, MLK Day is. So, who has the day off? And which businesses will be closed? Schools and many colleges will be closed for MLK Day, since the day is a federal holiday.

It’s easy to take your supermarket’s frozen food items for granted, and many shoppers peruse frozen items without a second thought about how they got there.

While most government functions will not be operating on Monday, most grocery stores, big box stores and restaurants will remain open. Major chain stores such as Target, Costco, Walmart, The Home Depot, Jewel-Osco and Mariano's will remain open on the holiday.
