The largest delivery company in the country will require its corporate employees to return to the office this spring, eliminating remote work.

In an internal memo, UPS announced it would be requiring employees to return to the office five days a week starting March 4, the Atlanta Business Chronicle reported.

"By adopting this approach, we recognize the ongoing commitment of our operators and other UPSers who have and continue to work in-person in our facilities five days and sometimes more per week as they deliver on our purpose by providing industry-leading service to our customers," the memo stated, according to the publication.

The company plans to bring workers back to corporate offices across the country, including its headquarters in Sandy Springs, Georgia. The company previously rolled out a hybrid work model last year that affected 3,600 workers at the campus, the Atlanta Business Chronicle reported. UPS is the second-largest public company in Georgia.

Last year saw a bump in return-to-office mandates, with 2 million workers under some type of in-person requirement as of August, Bisnow previously reported. Big companies like Google, Starbucks and Boeing have announced some type of RTO requirement. However, the mandates haven't appeared to have a significant impact on overall office occupancy yet.

Office usage didn't experience a major spike in the post-Labor Day period as some had hoped for but has seen slow increases, according to Kastle Systems' keycard swipe data. Office usage in the 10 markets Kastle tracks ticked up in October to a three-year high of 50.5% of pre-pandemic levels and then rose above 51% before dropping off around the holidays. Kastle’s data also shows that five-day office schedules have become somewhat rare, as occupancy on Fridays was down more than 20 percentage points from Thursdays.
