The person behind the new initiative is Rabbi Asher Idan, who has published "a warning to the public in haredi neighborhoods. "
"In any situation it's important to check that the foreign worker is not an idolater, and if it turns out that he is, he must commit before being hired to stop practicing idolatry secretly and openly, which is his duty according to the Seven Laws of Noah as well," the rabbi said. "Otherwise, we must not initiate any deal with him."
The Seven Laws of Noah are seven moral imperatives that, according to the Talmud, are binding for all mankind. They include the prohibition of murder, the prohibition of sexual promiscuity, the prohibition of eating flesh taken from an animal while it is still alive, etc.
He added that the new initiative was gaining momentum and that he hopes it would be adopted in all haredi neighborhoods.
