One of my employees resigned about 3-4 months before.At the time of resigning he had been registered for EPF and ESIC deduction and it was being deducted as per rule.Now he wants to rejoin but does not wants mandatory deductions of EPF and ESIC. My question is , is it possible to hire him in any form eg as a retainer, commission basis or consultant basis so that his mandatory epf and esic deduction can be omitted ?
