Worker health and safety is about making sure that the people who work in a place are safe and healthy while they are doing their jobs. Just like how parents and teachers want to keep children safe, bosses and people in charge of a workplace want to keep the workers safe.
When you go to school, your teachers make sure you have a safe classroom. They might tell you to walk and not run in the hallways and to use scissors safely. Similarly, at work, there are rules and guidelines to follow to keep workers safe. For example, factories have machines that can be dangerous, so workers have to be trained to use them safely.
In addition to safety, worker health is important too. Just like how you might get sick if you don't wash your hands or eat healthy food, workers can get sick if their working conditions are not good. This is why workplaces should have clean air and water, bathrooms, and safety equipment like gloves and helmets.
Sometimes, even when rules are followed, accidents still happen. When this happens, workers should speak up and tell someone in charge so they can get help. After an accident, the boss should investigate what happened and try to make sure it doesn't happen again.
In summary, worker health and safety is about making sure workers are safe and healthy while doing their jobs by following rules and guidelines, having good working conditions, and speaking up when something goes wrong.
