Credit Suisse has told unvaccinated staff in the U.S. to keep working from home.
The bank is pushing back return-to-office plans amid concern over a resurgent health crisis.
A full return has been delayed until mid-October, while workers without inoculations are to stay home until further notice.
That's all according to an internal memo seen by Reuters.
It's just the latest move by Wall Street firms to rethink office working plans.
Several have started enforcing stricter mask and vaccination rules, while trying to avoid a fierce national debate over workers' rights.
Goldman Sachs, Morgan Stanley and Citigroup have all made vaccination a mandatory requirement for entry into U.S. offices.
