Could someone please explain this to me?  My husband took a stress test and it showed stress where he was not at all lying.  After looking up some info, I found this... 
 
Subject to restrictions, the Act also permits polygraph testing of certain employees of private firms who are reasonably suspected of involvement in a workplace incident (theft, embezzlement, etc.) that resulted in specific economic loss or injury to the employer  

Does this mean he can be fired by his employer for the results? What are the laws protecting him? Can he re-take it? He was interogated for 2 hours after this because they "saw stress", which I don't understand at all--scrutiny is stressful!  I can't find any rights or laws regarding this anywhere at all, and would be grateful to anyone who can fill me in. 
 
I should note here, We had no idea this was such a dangerously innacurate means of law enforcement, it was him who suggested that the police be called about the situation (money stolen from his work) and said he would be happy to do a lie detector test if they offered one, he's an honest man and would never steal--he thought there would be no reason to worry, just wanted to prove his lack of involvement and help his company.  Now we're so scared he will lose his job two weeks before Christmas because of results that are, well, blatantly a lie. 
 
We are in Fort Wayne IN.
