I agree it depends on circumstances and time served with the company. For example, If an individual whom may be type-rated but not "current" joins a company, does the OCC course, LPC and then some line training just to get " current" and then leaves without just cause after a couple of months, they probably don't have a leg to stand on and should pay the " bond" for those elements. On the other hand, if the person stayed for say 12 or 18 months, earned revenue for the company, then I believe it is a completely different situation and pen to reasonable debate.
The former examples, usually those that have another offer in the "wings" if they can get an LPC and recency deserve to pay as they are just making problems for those genuine candidates that come later.
