it is reasonable to charge for training, or require to work for some time if the training allows you to get a higher paying job. but the cost of the training, and the time that you need to stay in the job afterwards need to be reasonable too. for example in germany, a 3-month training allows a 2 year binding to the job. repay clauses only trigger if the employee quits voluntarily and doesn't have a strong reason to quit. i couldn't find anything about the cost of the training, but i guess this should be industry average. pilot training is expensive everywhere, and medical training can be too i guess. but i would expect the training should allow you to demand a salary high enough to pay it off in a reasonable time. the first example in the article is clearly demanding to much. as is mentioned further down, $20,000 is the average cost, which for a two year binding would mean the cost/repay-value is about $830 per month. still seems high, but if the training allows you to demand that much more for your salary then it would be ok.
