Anthill,
Those that propose or suport the abolition of datal seniority are usually either:
1. Those who have already achieved a command and now want to remove the last obstacles that prevent them getting exactly what they want wrt bidding, leave, etc,
2. Those who want a command and feel that they should be entitled to jump the queue because they feel that they already meet their own definition of someone who's put in the hard yards previously, or are someone who's smart enough to get the job above others.
3. Those who've already jumped the queue and are trying to justify their actions.
I know in your post that you stated that you work for neither J* or QF etc... so these definitions probably don't apply to you. But I'll say again what I've said previously in another thread that talked about datal seniority.
Say it was YOU that wanted the command, and somebody who was younger, "better qualified"/prepared or who had been in the company for less time than you got the job. If you could put your hand on your heart, wish the person well and think to yourself "better luck next time .... i'll just have to work harder", then you have a case (and are probably a much better person than most on this BB.
