IMO employers may not be required to undergo mental health tests as they are under no pressure to make them go crazy (stated crudely). However, they may be provided education on how to treat a maid and more importatntly the recognition that a maid is also a human being wouldnt be out of place coupled with some serious punishments and I mean punishments irrespective of who or what you are for the offenders may bring down the number of offenses.
