In order to protect the interests of laid-off workers, many countries have passed "plant closing laws" to check up on the owners. The plant closing process may require proof that the operation is losing money, and could require the approval of a court of law.
為了保障資遣勞工權益，有些國家特別訂有「關廠法」，檢查廠方關廠程序，甚至規定一定要有虧損事實、還要經過法院批准才能關廠。
