Two Philadelphia Am Law 100 firms advised employees this week that starting Aug. 9, they will only be allowed in the office after becoming fully vaccinated and can prove it with a CDC vaccine card.

Faegre Drinker Biddle & Reath and Cozen O’Connor are the latest to join a growing list of Big Law firms that are asking firm personnel to be fully vaccinated if they want to work in the office, in light of the surge of delta variant COVID-19 cases. Both firms have also pushed back the date for bringing personnel back to the office in a hybrid work arrangement.
