If there is one thing that every workplace has but should not subject its employees to, it's hazards. It's impossible to eliminate hazards completely, and the majority of businesses do a good job protecting those who work for them. However, sometimes, employers aren't good about addressing problems and don't take care of hazards that could cause injuries.
One thing that you need to know is that you have a right to refuse to work if your workplace is dangerous and your employer won't take steps to fix the issue. The Occupational Safety and Health Administration (OSHA) states that if you think that the working conditions aren't healthy or safe, you need to bring them to the attention of your employer.
You'll be allowed to refuse to work on a particular task if it's in good faith; that means that you legitimately must believe you're in danger if you perform the task. You can refuse to do tasks if you asked your employer to eliminate a danger and didn't do so, if a reasonable person would agree that there is a danger of serious injury or death and if there isn't time to correct the hazard through the proper channels.
If you do refuse to work, ask to be assigned to different work and explain that you won't do the original job until the hazards are corrected. You must stay at the worksite until your employer asks you to leave. Then, your actions will be protected by law, helping you keep your job but stand up for your right to be safe at work.
