answer:Are you sure it’s not in the original contract you signed when you started the job? Just because you didn’t sign anything new doesn’t mean you aren’t still liable based on something you’ve signed previously. Also, keep in mind anything you might have signed when the class started (such as a waiver of some kind). Written contracts aren’t the only things that can create liability, though. If you made any sort of verbal agreement along these lines, for instance, you would still have to pay the company back. And depending on where you live, there could be a local regulation allowing companies to bill you for the classes. This is why it’s always best to be clear on the terms of a benefit before accepting it.
