Nothing changed, Previous rules better than this. because before 2 years ban, but not based on contract if it's 5 years means, it will ban for 5 years to change the employer.

Please explain, my current contract 5 years, but i completed 3 and 1/2 years of contact. also, i had now every one need to sing the new contract, that means can the previous contract will be cancelled or not? can i join with another employer with new contract?. Plz advice.
