it blazed a trail for similar policies in other industries.

Explanation:

The Adamson Act was a law passed in 1916 to prevent workers on the interstate railroad from being abused with hours of inhumane and exhausting work, so the law required workers to work only 8 hours a day and if it were necessary to work longer, they should receive an additional wage.
