Lead by example is the key here.
CC have been shafted, just like the rest of us. If the management can't make the effort to show these girls how much they are worth to the company, then it figures that they will not put in the effort themselves.
But looking at the bigger picture, these girls are still miles ahead of our competitors. Maybe I have been lucky to have ID flights where I have only seen excellent service from everyone involved. And maybe you have been unlucky to have had the crappy flights. Swings and roundabouts.
