probably not, no...

I think that would be classed as hearsay (sp?). Your boss would have to catch them in the act I reckon

Yes, if this person has actually been stealing from their employer, and you've simply brought it to their attention then the boss (Or rather the company, since it probably is the legal owner of whatever property was stolen, unless you work directly under the business owner, your boss is just another employee) has every right to fire/take legal action againts the accused theif. Of course though, if it is as you mentioned a case of she said/she said, then it wasn't a good idea on your part to get involved in the first place unless you had personally witnessed the supposed theft. For all you know, the co-worker who told you in the first place could have just been spreading false rumours about the supposed theif trying to get them fired, and trying to use *You* as a middle-man so they wouldn't get in trouble when and if the accusations proved to be false. You had no real way of knowing if it was true or not. I'd reccomend making it clear to your boss, if you haven't already, that the only information you were going on when you told them was the word of the person who told you, and that you wouldn't want to see an innocent person lose their job because of your mistake (I'm assuming here that you wouldn't). If you make that clear, then any legal action they take can't be based solely on your word, because any court of law would definitely classify it as heresay.

no, hear say isn't admissable in court he would need more proof.

unless there is a paper trail or an actual witness to the supposed thievery, your boss may have no actual proof........otherwise, this is heresay, which would not hold up in a court of law......take care....Brian.....
