Another note on ground handling operations.
It is a very profitable business when run properly, however, the hard workers see no rewards. I've seen sizeable amounts of cash being handed directly to managers from airline representatives, and then not seen much of it after that!
Also, ground crew place a fair amount of trust on flight crew during a/c pushback just as pilots place trust on ground crews.
With respect to the amount of training given, it isn't hard to say who you would trust the most!
More selective recruiting required, but will never happen. More usually a serious lack of applicants for the summer season means ground handling companies can't afford to be fussy. They just require the manpower in any form!
