I hope ya'll don't hate me for this but -
Seriously, the lady has 5 children....do you really want her to loose her job over $10? (You didn't mention how much you paid for the fabric.) Granted, what she did by violating company policy was WRONG and it's suspicious as to why she is now hiding from you. I just encourage you to pray about/think about what you really should do. And getting her fired isn't going to bring back your facric or your money. Just saying...........................
