Not seeing this at all. Are you watching the show? Justin, Pip, Biegs have all been close friends of Kristin's for 10+ years. She also gets back together with her friends in LA often, some of them, like Britney Field, date back to high school.
Kelly was in that circle. She & Kristin had been friends since Kristin moved to Nashville. Probably one of her closest friends because of that proximity so I understand why Kristin is hurt by the fallout. Watching how poorly Kelly handled it on camera, leads me to believe she's said worse off. Maybe she thought the show would make her a star? Who knows, I certainly don't miss her.
In terms of employees, no surprise there, especially with a growing company in the retail industry. Besides, I think that drama was what the show originally designed to be based around. It's proved far less interesting than than the lives of Kristin & Jay.
