Kristin - and Brittainy, to an extent - is very dismissive of her employees. On the one hand, I can see why. Most of them are gossipy, clique-y idiots who can't fill a box properly. And who cares if they don't like Kaylee? And they're in their early twenties, an age where you're more sensitive and prone to drama. But on the other hand, employees need to be feel that they're being heard, that they're valuable, etc. And being on the floor and doing the work means they have insight that the higher-ups don't.
Example #1 is when Brittainy said to shipping that they needed to do the shipping manual ASAP, because "taking a photo doesn't take long." On the one hand, she's right. But on the other, it's dismissive of the work it actually does take to put a manual together. It's a delicate balance between holding an employee's hand and acknowledging their efforts. And nobody in management on this show seems to realize that.
It's clear that the drama necessary for a reality show is harming day-to-day operations. Matt should have been out the door in a real business, but since he brings drama for the show, he stays.
