According to the 2014 Law on Social Insurance, Article 2, Clause 1, Point g says: "Employees going to work abroad under the contract specified in the Law on Vietnamese employees working abroad under the contract;" belong to the subjects of compulsory social insurance. Article 85, Clause 2, Point b, "Employees may make payment directly to social insurance agencies of localities where they reside before going abroad or via enterprises or non-business organizations that have sent them to work abroad." If so, I'm an instructor of employees working abroad under contract and contacted the local insurance agency. They said they collected only under voluntary insurance. Then, would it violate the law if the employee does not participate?
