Following the lead of other financial giants, Morgan Stanley announced on Tuesday that employees, who are expected back in the offices beginning July 12th, must be fully vaccinated and attest to their status by July 1st. Unvaccinated employees will continue to work remotely. This comes after a previous statement from the company that only employees in certain areas of the company have to be vaccinated. This mandate will also require vaccination attestations from clients and visitors to the NYC and Westchester County offices.
