Because Duolingo intends to require all employees to return to work from an office, all employees will need to be fully vaccinated against COVID-19 and have received any booster doses as recommended by the Centers for Disease Control and Prevention to remain employed unless they have an exemption to vaccination pursuant to a required reasonable accommodation. This is so that our employees feel safe in the office.
