I disagree.
Once a pilot has achieved his ATP, I believe it is more than reasonable that an employer pay for training. In fact (at least in the US), required initial training in a Part 121 carrier and training for a type rating are virtually identical. It costs no more for an employer to train a pilot "from scratch" than it does to train an already-type-rated pilot.
I wouldn't recommend anyone pay for a type rating unless he KNOWS that there is a job available that is contingent on the rating, AND requires no other experience in type. Right now, Southwest Airlines is the only such airline I am familiar with...
