Culture is about the way things are done within organizations. It's also about people's thoughts and feelings toward safety, their beliefs, attitudes and expectations regarding everyday actions. The way each person thinks and acts toward safety shapes the beliefs and behaviors of those around them.
Positive cultural changes in safety can start near the middle of the organization, where you're situated. Senior managers are in the best positions of leadership to help support long-term cultural changes that can improve morale, quality and productivity. But it's up to people like you to get things started.
