I just want to add that the biggest problem is the fear. If they don't have strong enough whistle-blower protection and it's not clear enough, they are afraid to come forward when they see things like shortcuts being taken, etc., because they know they're going to lose their job. Having a safe whistle-blower line is critical for the workers to have the confidence to report safety violations and other shortcuts that are being taken. Without it we will just continue the way we are.
