William Nuckles Doak (December 12, 1882 – October 23, 1933) was an American labor leader.

On December 9, 1930, Doak was appointed by President Hoover to serve as Secretary of Labor, succeeding Senator James J.

[1] He encouraged the passing of the Davis-Bacon Act, which determined the prevailing wage to be paid on a government contract or federally funded construction project.

Doak believed that removal of undocumented workers would reduce relief expenditures and free jobs for native-born citizens during the Great Depression.

[2] Though there is no evidence that Doak made any effort to single out any specific ethnic group, this resulted in the targeting of the Mexican community.
