If they are attending training such as a school, they should be paying you. If they are working for you, such as an apprentice would, you should be paying them. Why is that so hard to get. I was an Apprentice electrician before I earned my Journeyman Electrician license. I can tell you I was damn sure paid. And I can also tell you it isn't just as easy as getting as little training and running off to start your own successful business. Just like an apprentice electrician, a taxidermy apprentice is going to be doing work that is making your business a profit. Like Dennis said, even if they are sweeping the floor, they are saving you time to do other things.
