It's no surprise then that AINs lead the Workcover statistics in back and back related injuries. They share the same percentile of damage as coal mining does for men. They are thrown out the door and told to come back when well. Even if nurses do know their rights they still find themselves victimised mercilessly on return to duties. Permanent and severe damage results from any further trauma.
Damage done psychologically can be no less crippling.
Walking along any corridor causes an instinctive feeling of sadness. The things people like to do don't cease at the age of retirement. They still need to talk, chat, be cuddled, be cajoled, laugh, smile, show pictures of the grand kids and all those social aspects. But there's never enough time. Workers feel this and feel guilty themselves, often, adopting brusqueness as a cover.
