What benefit did the national labor union convince congress to pass just for government workers?

The National Labor Union successfully lobbied Congress to pass the Eight-Hour Workday Act in 1868, which mandated an eight-hour workday specifically for government workers. This legislation aimed to improve working conditions and promote a better work-life balance for federal employees. It marked a significant step in the labor movement, advocating for the rights of workers and setting a precedent for future labor reforms.
