Zammy, you've got employees of "Cartels" that can't fully work on their own equipment because only certain technicians get all of the training. My advice is to avoid proprietary units. There is plenty of work out there.
That is sad I know. One more way to keep the information "inside" the cartell is to keep the information away from own mechanics as well. And here they are claiming that one could simply contact them and ask...they do not eaven tell their own people. Unless You quilified as a "trusted" person.
I agree on that. I've been with a big four and training is somewhat self-development. You have to learn it yourself. What you only get is a simple safety training not to be caught in between
