Someone hiring you and not paying you is a breach of contract but that's not the same as piracy. If I download the latest Hollywood blockbuster for free, I've not breached a contract because I didn't enter into one (though I may have breached a contract with my ISP). The offense committed is copyright infringement and in many jurisdictions this is a civil offense rather than a criminal one (or, as in the US, there are conditions to turn it into a criminal one that very few downloaders would satisfy).
