What if janitorial/custodial employees work in the Port offices at nighttime when there are very few Port employees present?

All contractor employees, including janitorial/custodial workers, whether day or night shift, must be fully vaccinated if the contractor employees enter Port offices or federal leased spaces to perform work, and their presence is more than fleeting, even if a substantial portion of their work is performed outside of the identified Port offices. The trigger for the determination is whether their presence in the Port offices is expected to exceed 15 consecutive minutes.
