Ir. can kick ur salary from rm4500 to 6500 straighaway..

but that is in construction consultancy.. no idea about manufacturing line..

personally i think, for manufacturing Ir. is not a requirement.. as u dont involve in any endorsement (correct me)..

better for u to chase for business master first as it reflect ur management style more..

but if u still insist, like selrahc said, theres no harm chasing for Ir. ...

getting an extra recognition is never a problem
