FF, one would suggest that it is you that has no ambition. Making other collegues feel inadequate is the work of a common bully!
Why are you so critical of people that fly the Dash 8? I am not sure if you are aware, but it happens to be the majority fleet in the company, so therefore it is difficult for people to get onto it. Also a lot of current dash drivers have turned down the luxury of a 'Hot Meal' and a 10k payrise because they do not want to fly 'old technology'. You may be able to put jet hours on your CV, you can't put full EFIS experience!
