Seaman status in United States admiralty law
The status of a seaman in admiralty law provides maritime workers with protections such as payment of wages, working conditions, and remedies for workplace injuries under the Merchant Marine Act of 1920 (Jones Act), and the doctrines of "unseaworthiness" and "maintenance and cure". Each of these remedies have the same criteria for the status of "seaman".
