So, should the employer violate city ordinances? Because of the union contract?
Well let's look at it this way, as an employer i allow an unvaccinated employee work in violation of health and safety laws. Said employee gets covid then infects another employee who ends up in hospital and his wife or kids get infected by him and they die. In my state in Australia, an employer under the health and safety act would and should go to prison. The think about the compensation and wrongful death law suits
