What topics or categories of jokes shouldn't you discuss, tell, forward at work?

Keep workplace humor professional, inclusive, and respectful. Avoid jokes that target or demean people based on protected or sensitive characteristics or that create a hostile environment—including those involving race or ethnicity, gender or gender identity, sexual orientation, sexual or crude content, religion, age, disability, national origin, or politics. Also avoid harassing, discriminatory, offensive, or otherwise inappropriate content, and don't forward such material via email/chat. When in doubt, don't share it; keep humor light and appropriate so everyone feels included, consistent with company policy and anti-harassment standards.
