I'm sure they will not abolish the system of sponsorship. But they can consider some changes, which will help the employees like below;
1. Employee must work at least 2-3 years with the sponsor to avail the sponsorship.
2. The employee may pay back the expense incurred by the sponsor on getting release.
3. They can revise the 2 years re-entry ban to 1 year.
4. Employees should be deserved for the sponshorship change, if the employer breaks the labor law (Non payment of salary, ot, tickets etc)
5. Re-entry ban should be reduced to 6 months, who complete 5/6 years with the same sponsor
