Alternative to employment bond - trying to introduce some kind of employment security for new employees joining us

Hello all, I work as an HR in a software company. We are trying to introduce some kind of employment security for new employees joining us, but we are not keen on a bond. What could be the alternative to employment bonds? I have heard about companies taking cheques as a security;but i'm wondering if its legal in India. Kindly guide if there is any other way. Thanks

What you are planning take in written against Cheque received for what?

@Prashant, I meant I have heard companies taking cheques from employees while joining, and returning this after completion of said period. If the employee doesn't complete the said period with company, the company can encash the cheque.

Taking blank cheque as security is illegal and a kind of black mail technique.
Company can review its policies and make their organisation a nice place to work and retain employees.
