Those are the key words "THe company hires a known drug addict." Then I agree, the company is liable, only common sense. If you have a clean criminal record free of any questional history, why should the employer be held responsible for liability? If you pass the backround check OK, that should it. Now if the employee exhibits any signs of problems, then OK I can agree for further investigation. I'm not being unreasonable here, just trying to protect our constitutional rights of reasonable cause and search. I guess alot of people here feel that law doesn't apply to private entities. There seems to be end to the erosion of rights and liberties, just more excuses and reasons to violate them.
