Repeat after me: "I have a deeply held religious belief that I am not to take the experimental Covid genetic modification." You do NOT need to elaborate to your employer. *If* you want to elaborate to your employment law attorney (NOT) your employer, a few follow-ons off the top of my head are: ...it's the Mark of the Beast. ...I am forbidden from joining pagan religious cults, which my religion identifies the Covid cult as. The experimental genetic modification is a mark of membership in that religion, like a rosary, yamaka, praying towards Mecca, etc. ...it's made using murdered babies, and my religion prohibits me from benefitting from child murder. ...I was made in God's image and am not to engage in artificial genetic modification of that image. And so on. Covid is a religious cult. Religious people have a plethora of reasons to refuse to join it for the same reason that they'd refuse a discriminatory employer demand to wear a yamaka and go to the synagogue every Saturday.
