Most corporate values statements (e.g., "integrity") are unactionable and don't change internal culture. Effective leaders codify specific, observable behaviors—the "how" of working together. This makes unspoken expectations explicit and creates a clear standard for accountability that a vague value never could.

Ovitz observed that people who badmouth others, even their own partners, do so from a place of insecurity to make themselves look better. He implemented a strict "no badmouthing" rule at CAA to build a stronger, more positive culture.

Culture isn't about values on a wall; it's about daily habits enforced by memorable rules. Ben Horowitz argues that rules need "shock value," like A16z's policy of fining partners $10 per minute for being late to a founder meeting. This makes the underlying principle—respect—unforgettable and non-negotiable.

The actual standards of your organization are not set by posters or mission statements, but by the negative behaviors you permit. If you allow chronic tardiness or underperformance to continue without consequence, you are signaling that this is an acceptable standard for the entire team.

Your culture isn't what's on the walls; it's defined by the worst behavior you allow. Firing a high-performing but toxic employee sends a more powerful message about your values than any mission statement. Upholding standards for everyone, especially top talent, is non-negotiable for a strong culture.

When confronting a high-performing but abrasive employee, don't just criticize. Frame the conversation around their career. Offer a choice: remain a great individual contributor, or learn the interpersonal skills needed for a broader leadership role, with your help.

A company's culture isn't its mission statement; it's the worst behavior it's willing to accept. High-integrity employees will leave a toxic environment, while transactional, self-serving employees who tolerate anything for a paycheck will stay. This selection process causes a continuous erosion of culture.

Allowing a high-performing but toxic employee to thrive sends a clear message: results matter more than people. A leader's true impact and the company's real culture are defined not by stated principles, but by the worst behavior they are willing to accept.

When confronting a talented but abrasive CTO, don't just critique bad behavior. Frame the conversation around their effectiveness. Horowitz suggests saying, "You're a fantastic Director of Engineering, but not an effective CTO," because a true CTO must marshal resources across the entire company, not just manage their own team well.
