Implementation of a seafarer’s employment and social rights may be achieved by national laws or regulations, applicable collective bargaining agreements, other measures or practice, unless specified otherwise by requiring countries to adopt national laws and regulations to implement the provisions. Countries can determine if a particular provision should be in a law, regulation or subsidiary legislation (administrative orders / official marine notices).
A country may decide certain matters are handled better through other legal measures or collective bargaining agreements or through internal administrative instructions. Countries may determine no further legal measures are required if rights already exist in laws applied by national courts.
