Don't be silly, it's a common practice in some industries for a company to pay some expensive course in exchange for X (usually 2) years of work (paid, very well). You can leave whenever you want, you just have to pay back the course. I had a friend working for Airbus who just did that, the company he moved to offered to pay him back the cost of the bailing out. Though all the times I have seen this happening was for very specialised and well paid work, when the workers have quite a lot of leverage. It's not hard to imagine this becoming really bad if the worker does not have any leverage.
