Uber is reopening — well, opening — its new San Francisco headquarters Monday, albeit at limited capacity. Meanwhile, Facebook will begin allowing workers back into some of its Bay Area offices up to 10% capacity in May, and those offices may reach 50% capacity by September.

Facebook will allow workers to remain remote up to one month after their office returns to 50% capacity, and the offices will continue to require safety protocols, including masking and some ongoing testing, according to Bloomberg.

Mark Zuckerberg has said that he expects as much as half of Facebook's workforce will remain remote over the coming decade, though those who relocate out of the Bay Area may be required to take a pay cut.

Uber announced Friday that it will open its Mission Bay headquarters with 20% occupancy on March 29, though staff can return on a voluntary basis and the company's work-from-home policy does not end until Sept. 13. Uber had planned to move into the headquarters in early 2020, but the pandemic delayed that.

In a December note from Alphabet CEO Sundar Pichai, Google pushed back its return to offices to September 2021 and suggested that most employees may return in a hybrid model of at least three days a week in person.

Salesforce COO Bret Taylor said Thursday that the company was "very close" to reopening its San Francisco headquarters.
