Union Vice President Tim Leech said the city failed to properly notify and negotiate the vaccine mandate. The city and Pittsburgh Public Safety said Wednesday they do not comment on legal matters.

Since this mandate is for all city employees, it applies to Pittsburgh police officers and Pittsburgh firefighters.
