Multi-X, you have very valid concerns, and if the situation warranted it, I am capable of doing what has to be done. It is part of being an adult, of being a professional. What is maddening about these tossers (appropriate term) is their talent and luck for skating around the problems that would put them in the spotlight, that would get them into trouble. These are not the individuals who will get involved with flight controls or engine changes.
The problem is becoming more widespread, as you said. We are getting many new hires that are upgrades from other departments, such as baggage handlers and cleaners, who went to school to get a certificate so they could jump to a higher pay scale, not because of any mechanical calling.
Some work out, but most bring too much luggage and attitude from their previous airline positions. It makes one appreciate the people who join up with actual talent and ability.
