The Union of Orthodox Jewish Congregations of America (UOJCA), more popularly known[Notes 1] as the Orthodox Union (OU), is one of the oldest Orthodox Jewish organizations in the United States. It is best known for its kosher certification service. Its circled-U symbol, Ⓤ, a hechsher mark, is found on the labels of many kosher commercial and consumer food products.
The OU supports a network of synagogues, youth programs, Jewish and Religious Zionist advocacy, programs for the disabled, localized religious study programs, and some international units with locations in Israel and formerly in Ukraine.
The OU was founded in 1898 by Rabbi Henry Pereira Mendes, and it serves today about 1,000 synagogues and congregations of varying sizes. The need for a national Jewish Orthodox rabbinical organization in the early twentieth century was recognized by a number of groups. The Union of Orthodox Rabbis was the most powerful rabbinical body at that time and many of its members saw great value in establishing the early Union of Orthodox Jewish Congregations of America.
Originally, the OU was formed by the same rabbis who created JTS, the Jewish Theological Seminary. JTS started as an Orthodox institution to combat the hegemony of the Reform movement. At the time, there was no Conservative movement by name, though there was a range of liberalism within Orthodox Jewry. Cracks between the OU and JTS first formed in 1902, shortly after Solomon Schechter's recruitment from Great Britain to head JTS. Schechter "liberalized" the institution and its approach to Torah study. Most of JTS's original founders, backers, and staff disavowed the changes, seeing it as headed toward the very philosophy JTS had been intended to hedge against. Exactly 100 days after Schechter's arrival, they formed a new Orthodox group, Agudath Harabonim, which refused to recognize the rabbinical credentials (Semicha) of those ordained at JTS, though Agudath explicitly wrote that the pre-Schechter graduates of JTS were fine rabbis and welcome.
Without their support, Schechter broke away from Orthodoxy to create the Conservative movement, with JTS as its predominant agency. Conservative Judaism created its own competing synagogue movement in 1913 with the formation of the United Synagogues of Conservative Judaism (USCJ). While not holding strictly to traditional Orthodox interpretations of Jewish law, Conservative synagogues still maintained much of the "look and feel" of the Orthodox synagogue, but did away with the strict gender separation during prayer services which was observed in Orthodox synagogues as a religious obligation. The USCJ actively competed with the OU for synagogue members and succeeded in recruiting many formerly Orthodox congregations, especially during the post-World War II years, when many of those congregations moved away from inner-city Jewish neighborhoods into the newly established suburban Jewish communities.
Conservative Talmudic scholars sought to find justifications in the rabbinic literature for these and other compromises in Jewish law halacha which they instituted over time in synagogue practices and other mitzvah observances which widened its theological differences with the Orthodox establishment. One of the clearest breaks between Orthodox Judaism and Conservative Judaism was the "Sabbath decision of 1949". This unprecedented decision, which emerged from the Rabbinical Assembly, the rabbinic arm of the Conservative movement, allowing Jews to drive to synagogue (shul) on the Sabbath if they lived too far to walk, made untenable any claim that both camps adhered to the same principles of defining halacha. However, because the OU had no means of enforcing specific religious standards upon its member synagogues, some of them took down the mechitza (separating barrier) between the men's and women's sections during prayer services, while still calling themselves Orthodox and maintaining their membership in the OU. Similarly, it was common during the era for Jews who were not Orthodox in practice to retain their membership in an Orthodox synagogue, motivated by family loyalty, convenience, nostalgia, social obligation or politics.
During the early decades of its existence, the Orthodox Union was closely associated with and was a supporter of the development of Yeshiva University into a major Jewish educational institution producing English-speaking, university-trained American rabbis for the pulpits of OU synagogues. Some Orthodox rabbis viewed the nascent OU and the rabbis of its synagogues as too "modern" in outlook, and thus did not participate in it, instead setting up their own more stringent rabbinical organizations.
Nevertheless, the idea for a national Orthodox congregational body took hold. The OU was soon acknowledged within the American Jewish establishment as the main, but not exclusive spokesman for the American Orthodox community. Representatives of 150 Orthodox congregations, with an estimated membership of 50,000, participated in the OU's 1919 national convention. The OU became more active in broader American Jewish policy issues after 1924, when Rabbi Dr. Herbert S. Goldstein, the innovative spiritual leader of the West Side Institutional Synagogue of Manhattan became the president of the OU. Under Goldstein, the OU and its Rabbinical Council (a forerunner of today's Rabbinical Council of America, became a founding member of the Synagogue Council of America, along with representatives of the Reform and Conservative movements and their rabbinic affiliates.
The OU played an active role in advocating for public policies important to Orthodox practice, such as advocating for the five-day work week and defending the right to kosher slaughter. It was also involved in efforts to serve the religious needs of American Jewish soldiers as well as relief for European Jewry.
In the 1920s the OU started its Kashruth division, establishing the concept of community-sponsored, not-for-profit kashruth supervision. In 1923, the H. J. Heinz Company's Vegetarian Beans became the first product to be kosher certified by the OU. The OU's kashruth program was heavily influenced by Abraham Goldstein, a chemist who used his knowledge of food science to determine the kosher status of various products. (In 1935, Goldstein left the OU and started his own organization, Organized Kashruth Laboratories, the OK.) The wide acceptance of OU kashruth supervision rested largely upon the outstanding reputation of its rabbinic administrator, Rabbi Alexander S. Rosenberg. He and his staff established effective kashruth supervision standards for modern food production technology which made possible the explosion in the availability of OU certified packaged kosher products across the US since the 1950s.
By the mid-1930s, the OU kashruth division had matured enough to influence and challenge the traditional local rabbinic "sole practitioner" kashruth supervision model. At the time, kashruth was a profitable business for rabbis; the OU sought to make kashruth freely available, to reduce the consumer cost of keeping kosher.
The OU Women's Branch was also organized during the 1920s to encourage the formation and support of active sisterhoods in OU synagogue's. Women's Branch took on a number of special products, typically related to women's Jewish education and support for Yeshiva University.
OU operations became more efficient with the appointment in 1939 of Leo S. Hilsenrad as its first full-time professional executive director. Its services were further expanded in 1946, with the addition of Saul Bernstein to the professional staff. Bernstein became the founding editor, in 1951, of Jewish Life the OU's popular publication for Orthodox laymen. Bernstein also succeeded Hilsenrad as the OU's administrator.
During the postwar years, there was considerable overlap in the lay leadership of the Orthodox Union and Yeshiva University. The Orthodox Union expanded its operations following the election in 1954 of Moses I. Feuerstein as its president. Its leadership ranks were augmented by a talented group of lay leaders including Joseph Karasick, Harold M. Jacobs and Julius Berman, who would guide the OU's growth over the next several decades.
Another major development was the appointment, in 1959, of Rabbi Pinchas Stolper as director of the Orthodox Union's youth group, the National Conference of Synagogue Youth (NCSY). By inspiring thousands of public-school educated high school youth across North America to become more observant, NCSY played a major role in launching the Baal Teshuva movement, a widespread spiritual re-awakening among Jewish youth which followed the 1967 Six Day War. 
By the mid- to late-20th century, most synagogues affiliated with the Orthodox Union were under the leadership of rabbis trained by Rabbi Joseph Soloveitchik at Yeshiva University's Rabbi Isaac Elchanan Theological Seminary. These rabbis were ideologically Modern Orthodox. By the 1990s and early 21st century, the OU's general philosophy and levels of observance may be seen to have shifted towards stricter interpretations and halachic practices. This change has not necessarily affected individual member congregations, but has impacted many Orthodox Jewish communities across America. The general trend toward stricter practices among Orthodox Union congregations reflects American Orthodoxy's trending toward Haredi Judaism.
OU's board of directors has had female members since the mid-1970s.
In 2009, Rabbi Steven Weil of Beverly Hills, succeeded Rabbi Tzvi Hersh Weinreb as the OU's Executive Vice President. In 2011 Rabbi Simcha Katz became president.
In 2014, the first women were elected as national officers of the OU; specifically, three female national vice presidents and two female associate vice presidents were elected.
In 2017, the OU adopted as formal policy the normative Orthodox position that clergy is only for men. It precludes women from holding titles such as "rabbi", or from functioning as clergy in its congregations in the United States.
Alliance with the Rabbinical Council of AmericaEdit
For many years the OU, along with its related rabbinic arm, the Rabbinical Council of America, worked with the larger Jewish community in the Synagogue Council of America. In this group Orthodox, Conservative and Reform groups worked together on many issues of joint concern. The group became defunct in 1994, mainly over the objections of the Orthodox groups to Reform Judaism's official acceptance of patrilineal descent as an option for defining Jewishness.

The Orthodox Union's Kosher Division headed by CEO Menachem Genack, is the world's largest kosher certification agency. As of 2017, it supervises more than 800,000 products in 8,500 plants in 100 different countries. 200,000 of those products are found in the US. It employs 886 rabbinic field representatives, mashgichim in Hebrew, and about 50 rabbinic coordinators who serve as account executives for OU-certified companies; they are supplemented by a roster of ingredient specialists, flavor analysts, and other support staff. The supervision process involves sending a mashgiach to the production facility to ensure that the product complies with halacha (Jewish law). The mashgiach supervises both the ingredients and the production process.
In 2005, an undercover video purportedly showed cruel treatment of animals in an OU-certified slaughterhouse. The story was featured many times in national newspapers and in Jewish media. The OU defended its limited scope of supervision, while studying changes to its policy. In 2006, the OU's response was the subject of a video narrated by Jonathan Safran Foer, Irving Greenberg, and David Wolpe.
National Conference of Synagogue YouthEdit
The international youth movement of the OU, (NCSY), was founded in the early 1950s. After a few false starts, NCSY first achieved success under Rabbi Pinchas Stolper by reaching out to public school educated Jewish youth with a message of Orthodox Jewish religious inspiration. It has now expanded its reach to include many already religious mostly Modern Orthodox children attending Jewish day schools. Many marriages have resulted from the social interaction. NCSY boasts that 95% of their members marry other Jews.
Orthodox Union Advocacy CenterEdit
The OU Advocacy Center is the non-partisan public policy arm of the nation’s largest Orthodox Jewish organization‚ representing nearly 1,000 congregations nationwide, and leads the OU’s advocacy efforts in Washington, DC, and state capitals. Formerly known as the Institute for Public Affairs, OU Advocacy engages leaders at all levels of government as well as the broader public to promote and protect the Orthodox Jewish community’s interests and values in the public policy arena. In June 2018, Attorney General Jeff Sessions spoke at the OU Advocacy Center's annual conference in Washington, where he was presented with an artistic rendering of the biblical command “Justice, justice shalt thou pursue.” Given Sessions' policies, particularly those concerning immigrants and asylum seekers, the OU came under significant criticism for hosting him and presenting him with the plaque.
The OU requires that all member synagogues follow Orthodox Jewish interpretations of Jewish law and tradition. Men and women are seated separately, and nearly always are separated by a mechitza, a physical divider between the men's and women's section of the synagogue. Many OU synagogues support the concepts of Religious Zionism, which teaches that the existence of the State of Israel is a step towards the arrival of the Messiah and the eventual return of all Jews around the world to live in the ancient national Jewish homeland. The laws of Shabbat (the Sabbath) and Kashrut (dietary laws) are stressed. Members of OU synagogues have a diverse political background, and are not necessarily members of any one political party. Orthodox Jews tend to be more politically conservative than the rest of the Jewish community. They daven (recite prayers) in Hebrew, using the same traditional text of the siddur (prayer book) that has been used in Ashkenazi and Sphard Jewish communities for the last few centuries. Until recently the most popular English translation of the prayer book used in OU synagogues has been Ha-Siddur Ha-Shalem edited by Philip Birnbaum. In recent years the most popular translated siddur has been the Rabbinical Council of America edition of the Artscroll siddur. Until recently the most common Hebrew-English Humash (Five Books of Moses) used has been the Pentateuch and Haftarahs, edited by Rabbi Joseph H. Hertz; in recent years this has been supplanted by The Chumash: The Stone Edition, also known as the Artscroll Chumash.
Yachad - The National Jewish Council for Disabilities, is a 6,500 global organization dedicated to address the needs of all Jewish individuals with disabilities and ensuring their inclusion in every aspect of Jewish life. The inclusive design aims to ensure that persons with diverse abilities have their rightful place within the Jewish community, while it helps to educate and advocate for the Jewish world for greater understanding, acceptance, outreach, and a positive attitude towards disabled persons.
The Orthodox Union has been in two notable abuse scandals:
Baruch Lanner abuse scandalEdit
The OU may have ignored multiple reports of child abuse when appointing Rabbil Baruch Lanner as Director of Regions of its National Conference of Synagogue Youth movement. Lanner was ultimately convicted of multiple counts of sexual abuse and imprisoned. In response to the scandal, the OU implemented several new initiatives to better protect children under their care. 
In May 2008, the U.S. Immigration and Customs Enforcement (ICE), together with other Federal agencies, raided a kosher slaughterhouse and meat packing plant in Postville, Iowa, owned by Agriprocessors, Inc. At the time the OU provided kosher certification services to the plant. The raid was the largest single raid of a workplace in U.S. history and resulted in nearly 400 arrests of immigrant workers with false identity papers, many of whom were charged with identity theft, document fraud, use of stolen social security numbers, and related offenses. Some 300 workers were convicted on document fraud charges within four days. The majority served a five-month prison sentence before being deported. The OU had numerous rabbis working on premises, yet none reported child workers working illegally at the plant or the abusive conditions workers faced on site.
Even after the raid, the OU opposed imposition of minimum moral standards in order for products to be certified as kosher.
- The Orthodox Union has been known by several names, sometimes simultaneously. It has been called the Union of Orthodox Hebrew Congregations of America, the Union of Orthodox Jewish Congregations of America, and the Union of Orthodox Jewish Organizations of America.
It was originally called the Union of Orthodox Jewish Congregations of America. In the early 20th century, Jews were often called Hebrews; the Reform counterpart to the Orthodox Union was originally called the Union of American Hebrew Congregations. This caused occasional erroneous substitution of Hebrew for Jewish in the Orthodox Union's name.
The formal title was typically shortened to Orthodox Union or OU. This was so common that many never realized that this was not the official name. In addition, as the OU's scope expanded, synagogue services became an increasingly smaller part of its focus, and the formal name no longer made sense. The name was officially changed to just Orthodox Union in the early 21st century.
