That document which you sign presumably stays confidential between the retailer and you (i.e. a perspective employer won't see it).
The article also states that:
If someone started to take the course and paid for it—if they change their mind and they want to get their day in court, we’ll refund their money and put the case back in the retailer’s hands. They’ve got multiple opportunities to step back from this.
So I'm not sure how the two of those square.
I'm not vouching for this sort of practice (and it's probably been abused) - but it may in fact be preferable for a dumb young teenager/adult, to take an online course, than to have theft on their criminal record (that would probably make it pretty hard to find employment, even at a crappy job).
