Be good to your team
First you have to build a good team. Once you’ve got that, be good to them so they’ll stick around. There’s no doubt that Olivia will go to bat for her gladiators. And in return, they go to bat for her.
This doesn’t mean you need to be a pushover. Or agree to things that are to the detriment of your career or the business. But build a rapport and a respect between yourself and others so that when you do have to get tough, they understand.
