Rabbi Haim Kanyevsky told yeshiva administrators, “We are war with them
[Arabs],” therefore “according to Jewish law it is prohibited to hire them,”
according to Yom Chadash. Yeshiva administrators, after the Mercaz Harav
Yeshiva attack, asked Kanyevsky whether they should fire their Arab employees.
Kanyevsky, who expressed surprise that Arab workers were preferred to Jews,
asked, “Are there no Jews who can work and earn a living from the same work?”
He said that under normal circumstances it was always preferable to hire
Jews rather than Arabs, unless there was a significant difference in cost.
But in the present situation, due to the danger to Jewish life, there was
a prohibition against hiring Arabs, he said.

Kanyevsky’s ruling is likely to result in a mass firing of Arab employees
at hundreds of haredi yeshivot across the country.
