The City of Philadelphia continues to work to implement its workforce vaccine mandate previously announced in November 2021. While the City issued a vaccination mandate for all employees—those represented by unions and those unrepresented (exempt)—it is important to understand that legally the City must negotiate the impact of this new requirement with its labor union partners: the Fraternal Order of Police (FOP), AFSCME District Council 33 (DC 33), AFSCME District Council 47 (DC 47), and Local 22 (Firefighters) before it officially goes into effect for employees represented by those unions.
