Ultra-Orthodox is not the preferred term, but I know a Hassidic Jews who is a semiconductor engineer, another who works in a meatpacking plant, a jeweler, and a deli owner. Many Hassidic Jewish men are rabbis, but there are not that many jobs for Hassidic rabbis, so they have day jobs doing other things. The man in the meatpacking plant does kosher slaughter. Another job is mashgiach -- that is, kosher supervisor. A Hassidic friend of mine travels around the upper midwest inspecting food-processing plants to verify that their product can legally be marked as kosher. He certifies things as varied as breakfast cereal and whiskey. (Why not ultra-Orthodox? Because observant Modern Orthodox Jews are no less Orthodox and because the things that make Hassidic Jews distinctive are not their degree of orthodoxy but rather, their distinctive social norms that set them apart from the larger community.)
Haredi Jews are ultra orthodox Jews found around the world.
Orthodox Jews are strictly observant. Hassidic Jews are even more strict.
Orthodox and Ultra-Orthodox Jews are strict followers of Jewish law.
It's NOT a costume, it's a dress code, depending of which group Ultra-Orthodox Jews come from.
They're called "Ultra-Orthodox Jews". They are fanatical about traditional Jewish behavior and attitudes.
yes for ordodox and ultra-orthodox jews reform jews might adapt the rules of shabbat
Saturday is the Sabbath in Judaism. Orthodox (and some non-orthodox) Jews will not work. Many non-Orthodox Jews will work, but still remember the Sabbath day in their own ways. (And yes, there are some Orthodox Jews that work on Saturdays, but they do not advertise this fact).
Of course, Hassidic Jews emphasize the fact that they raise their children as Hassidic Jews, but in reality, there is significant intergenerational flow, with some children of Hassidic Jews departing for other streams of Judaism, and with some children of Liberal Jews joining more Orthodox streams. This seems typically human. There is a similar intergenerational flow between Christian denominations.
Haredi (Ultra-Orthodox) Jews believe in living by the Torah 100%
No, there were and are 12 tribes. The Ethiopian Jews are believed to be descended from Jews who traveled throughout Africa.
They believe their own way is the ONLY way to practice Judaism.
It depends on which denomination within Judaism you are talking about. Non-Orthodox Jews generally follow the customs and social norms of the society they live in. Orthodox Jews vary. Strict, "ultra-orthodox" Jews have no dating at all. They generally rely on parents or other family to help find potential spouses. Modern Orthodox Jews may date, but it depends on the family and some families will require a chaperon.
