Some of you are missing my point. I agree fatigue is a serious issue that needs to be addressed. And I agree it does happen. What I'm saying is don't use statements such as 'forcing them to work for 20 hours without an adequate break'; because I don't acceept that is correct. If I'm wrong go on prove it, show me the evidence of that roster. If you can't, management, the authorities and the public will just ignore you. And don't use fatigue as an excuse if you could/should have mitigated against it.
