You are either lying about the statistics at your company, or you are supporting a management that hires and trains incredibly poorly.
Any respectable Pilot, HR or training department would be ashamed of those statistics. Not defending them. Where are you finding these people and how are you training them ?
Or the other alternative is that the T & C's being offered by Guppies company are so poor that they only attract the dregs and it is up to the training department to try to separate those with any promise. This would also explain Guppies insistence that low pay does not equate to a lesser quality airman.
