How about trying to engage with them as human beings with all their shortcomings. Some may be more resistant than others, some may need some serious attitude readjustment. Some may just be recidivist.
While some of this is true, it's also unfortunate that the "some" happen to occupy places in the organization that are very effective at protecting the divisive, exploiting the innocent and pandering to company executives.
Plainly, it has to stop.
There has to be a point where proper engagement with ALL stakeholders takes place to reach agreement on how to mend the system.
As we aren't there yet, a Senate Inquiry isn't a bad start.
