So for workers who have a fixed duration contract with their companies (not unspecified/unlimited), it means they can switch their company without NOC at the end of the contract if they decide not to renew it. This is a significant change for those who are affected. BUT it is not clear whether their existing contract should be under the new system, or whether the rule will be applied once they have made a new contract under new system. In other words... (MAYBE) if you currently have a limited duration contract, you still face a 2 year ban if you quit your job after completing the duration of contract.
