If a business owner..................

[Doot]

Has an process within the business he knows is hazardous, but does not make said employees aware....... Should those employees have any repercussions? Or are the employees at fault for not practicing their due diligence?

It's on the employer to let everyone know the hazards of the job. Once they have been told though it is then the employees responsibility to use due diligence and be aware of there surroundings.

If the employers knows and does not make employee aware then they are liable.
