A yellow shield with symbols inside of it made out of a ruler and compass. The shied has green text in a yellow box to the right and left of it plus yellow text circuiting around it. Everything is set against a green background.
The Latin phrase "Work Conquers All" was the motto of California Bay Area based Furniture Workers' Union, Local 3141, which was part of the United Brotherhood of Carpenters & Joiners of America (UBCJA). The union was organized on 4 August 1934 and the UBCJA chartered the union on 3 April 1935. It represented furniture and bedding industrial workers. Local 3141 merged with Millmen's Local 42 and the Shipwrights Local 1149 in 1988 to form Carpenters' Union Local 2236.
The motto remains the UBCJA's motto. The UBCJA formed in August 1881 in Chicago, Illinois as the United Brotherhood of Carpenters. UBCJA's first general secretary and co-founder of the American Federation of Labor, Peter J. McGuire, helped get Labor Day established as national holiday in the US.
