Citigroup has asked all of its U.S. employees to start coming back to the office at least two days a week starting March 21, according to news reports.

"Although COVID-19 may never fully go away, we are seeing promising developments," Citi's head of human resources Sara Wechter said in the memo seen by Reuters.

Citi began returning staff to the office last September, including at its New York City headquarters and other offices in the tri-state area, the newswire writes.

In January, Citigroup said it would put any employees not vaccinated by January 14 on unpaid leave and fire them if they still don’t get the vaccine by the end of January, as reported.

As of the end of January, 99% of the company’s U.S. staff have been vaccinated, according to Reuters.

Meanwhile, Citi’s chief financial officer Mark Mason and investment banking head Paco Ybarra have tested positive for Covid, Reuters reported on Monday. The news has forced the firm to hold its investor day, taking place on Wednesday for the first time in five years, as a virtual event, according to the news service.

"We believe a virtual format is the right decision given our circumstances," chief executive officer Jane Fraser told Reuters in an email.

Financial services firms have been bringing back staff since the spike seen in Covid cases at the end of last year has subsided.

Early last month, Wells Fargo said it would bring most of its staff back on March 14, and that most would be able to work on a hybrid model going forward.

At the end of February, Charles Schwab and Edward Jones set their return-to-office dates for April 25.
