Which document outlines an employee's rights regarding workplace safety?

The Employee Right-to-Know Act is the correct answer because it specifically focuses on informing employees about their rights regarding workplace safety and health hazards. This legislation mandates that employers provide employees with information about the hazardous substances they may encounter at work, along with details about the proper safety measures to follow. The act empowers workers by ensuring they are aware of their rights to a safe working environment and the information they need to protect themselves from potential risks.

The other options do play roles in workplace safety; however, they do not specifically outline the rights of employees in the same way. The Occupational Safety Standards Document generally contains guidelines and regulations but may not directly address employee rights. The Workplace Safety Policy is likely to detail procedures and standards within a specific organization, but it is not a legal framework outlining employees' rights. The Employee Handbook can contain various information regarding workplace policies, including safety, but it is not specifically aimed at outlining safety rights like the Employee Right-to-Know Act.
