Simply stated, while sounding good, it seems silly. It sounds like, well, let's try this cookie cutter a different way, into the same dough.
You make it sound like she is uncontaminated, yet, you proffer credentials that are no different than anyone else.
Just because someone is "unknown" matters not whether that person is competant or will bring about change, as you suggest. While I commend your attempts at "opening doors" to unknowns, perhaps the way to break the ugly cycle we seem to have bought into, perhaps we should temper those with _real_ motivations to do good with new individuals.
I am biased, but I know that TG has always maintained, within the limits imposed by her "bosses", a mentoring program, something I have never seen elsewhere at USAirways. That, in itself, is something worth preserving. It provides an incentive to think globally rather than just for oneself. It is darn hard and there are pitfalls. But, correctable mistakes should be tolerated, if learning occurs, something I have yet to see at this company. It is that lack that helps debase our workplace to the sewer it currently resides.
There is another problem. It is too easy for a novice to buy into the inclusiveness sold by management, or even their own union. It takes someone who can tell mgmt or the union to f*off, even when you feel you might be alone. Then it takes a special person that can forge a working relationship afterwards. That takes training and experience.
I'd like nothing better than someone else to "take the reins", but I also know that would be a crap shoot for the FAs of PHL. You may get a great team, but, as I have been around the bend more times than you, I doubt it.
You want to roll the dice? Fine, T., you have nothing to lose, but what about the rest of the FAs in PHL?
