Preventing a person getting employed elsewhere may be possible in instances when ref./back ground checks are invoked by prospective employers by passing on unpleasant/unsatisfactory reporting. There are also bonds and other terms & conditions of employment which prohibits exiting employees from seeking employment with competitors or co.in the same field. Generally such restrictions will not stand to test of law in courts. For those not facing such pre-conditions things may be comfortable.
