Returns to office will be organized by job function and location, according to the memo seen by Reuters.

The biggest banks in the world are slowly re-opening their offices, emboldened by aggressive vaccination drives and falling COVID-19 cases in major financial hubs.

Operations and contact center employees will begin to return to their locations on a shift basis, working some days or weeks from office and others remotely, Powell said.

The rotational schedule is expected to be temporary, he added.

Most technology employees will be invited back to offices in October and the majority will be allowed more flexibility to work remotely, according to the memo.

Wells Fargo will also start collecting vaccination status from employees from July 19.
