Goldman Sachs and Credit Suisse have strengthened vaccine requirements for US employees and their American offices.
Goldman Sachs told staff anyone entering its US premises must be vaccinated and asked workers to wear masks in offices from Wednesday, even if they are vaccinated, according to an internal memo seen by Reuters.
Double jabbed staff members will receive weekly coronavirus tests from September 7.
The bank had previously asked employees to disclose their vaccination status.
Meanwhile, Credit Suisse has mandated all unvaccinated US staff to work from home from the same date.
Rivals Morgan Stanley and Citigroup have also introduced vaccination requirements for office workers, while JP Morgan, Bank of America and Wells Fargo have not.
Elsewhere, three employees at CNN were fired for visiting the news organisation’s offices without having had a Covid-19 jab.
“Everyone from news, sports and studios who comes in now and going forward must be vaccinated. We have been clear about this for months, so there should be no confusion,” CNN president President Jeff Zucker told staff.
