Respectful
Poor workers sometimes are judgmental about other workers/customers. Do not allow yourself to make false (stereotypes) about blacks, Latinos, women, sexual orientations, previously incarcerated individuals, minorities, workers with less formal education, wealth standards, and other common negative gossip-like views.
Good workers stay focused on helping the company to move (sell) its products and lower cost (save money) where possible. Maintain a level of self-respect and do not slip into false beliefs about others and you will be a highly effectively and valued worker.
