In March 1833, Ashley introduced the Ten Hours Act 1833 into the Commons, which provided that children working in the cotton and woollen industries must be aged nine or above; no person under the age of eighteen was to work more than ten hours a day or eight hours on a Saturday; and no one under twenty-five was to work nights. However the Whig government, by a majority of 145, amended this to substitute "thirteen" in place of "eighteen" and the Act as it passed ensured that no child under thirteen worked more than nine hours, insisted they should go to school, and appointed inspectors to enforce the law.
