"Also the more employable guys would be the guy with a GV rating"
You have got to be kidding my friend. Have you had a trawl through the recruitment agency sites?, I have . There is nothing out there unless you are type rated and current on the A320 /B777/B747 and are willing to move to Vietnam. I happen to be rated on the 747 but no longer current, the reply? not interested. There are a hell of a lot of qualified people out there chasing very few jobs. The GV rating is as useful as a chocolate teapot at the current time.
Suitcase man has it right. Seniority means nothing as in zip if the company decide to do it any other way. I was in exactly the same situation several years back. As for seniority, its never done me any favours. Didn't protect me when I had it and kept me back when I didn't. As I'll be hurled through the doors quicker than hot snot in August, please don't come the "its the only fair way" with me. Its bullsh@T and aviation is the only industry where "buggin's turn" is still seen as the way forward.
Bitter? me? you f*****g well bet I am.
