Step-by-step explanation:
The correct answer to the question of when you must create a workplace label is when b) You are using a new product. Labels are an essential part of workplace safety and are typically regulated by health and safety guidelines within an organization or by national safety regulations such as those laid out by the Occupational Safety and Health Administration (OSHA). It's crucial to label new products so that everyone in the workplace is aware of any potential hazards associated with that product, and knows how to handle it properly. Creating workplace labels is not a matter of personal timing or preference, but rather a requirement when introducing a new product into the workplace environment.
Understanding the values, beliefs, and unspoken norms in your organization will help you to fit into the new work environment. Observing how your coworkers and supervisors handle various situations can inform you about workplace expectations. This is true whether it's about arriving early or staying late, appropriate professional behavior, or even how to safeguard oneself, such as needing to wear an oven mitt to take a cake out of the oven. Workplace safety and proper ethical behavior are crucial in every work environment.
