If I work at 2 different companies in Vietnam, how do I join insurances?

In Clause 1, Article 42 of Decision 595/QD-BHXH in 2017, it is stipulated:

1. An employee who signs at least 2 labor contracts with different employers shall pay social insurance contributions and unemployment insurance premiums according to the first labor contract, pay health insurance premiums according to the labor contract with highest salary and pay premiums of occupational accident and occupational disease according to each labor contract.

Thus, according to the above regulations, if employees sign labor contracts in many places, they will pay social insurance and voluntary insurance in the first place to sign the contract. Health insurance will be paid at the place with the highest salary. As for labor accident and occupational disease insurance, they must participate in all places where they enter into labor contracts in Vietnam.

Best Regards!
