I suppose you should blame some of your colleagues who have taken a rating and line training and
off after they got 500 hours on type, or decided they should be flying an A380 after 18 months on the ATR. The word "free" doesn't exist when airlines are spending serious money on typing and line training you, and being businesslike they expect a return on their investment.
Some bond for the type rating, some others bond for line training if you have the type on your licence. It depends on where you work, but some countries will not allow an airline to bond pilots for any more than the actual cost of rating and line training. In some countries, bonds aren't worth the paper they are written on, so the training cost is taken out of your salary over the first 3 years or so.
So, it's a good question to ask, but the context is important.
