Leaders: Who's Shaping Your Company's Culture?If corporate culture starts at the bottom, you're in trouble.

I'm a woman in a male-dominated industry. When I was an employee, I could roll as one of the guys. Now I own a company, and an unpleasant bro culture has emerged here. I can't hang with the guys (I'm the boss, after all), but I also can't seem to influence their behavior. What do I do?

You've spent more time being "one of the guys" than being at the top, so here's a helpful reminder, in case you're feeling wistful: When you're one of the guys, you're fitting in -- which is the opposite of being a strong leader. As CEO, you can't have a sense of belonging. You need to flip that on its head and create a place others want to belongto.Every leader makes mistakes, and it seems you've made your first big one: You hired a team and then let them dictate the company culture. Now you need to fix that.
