Which of the following are duties of an employer under employment law?

The correct answer is that employers have a legal duty to provide a safe workplace and avoid discrimination. This reflects fundamental requirements in employment law that are aimed at protecting employees' rights and well-being.

Under various employment laws, such as the Occupational Safety and Health Act (OSHA), employers are required to ensure that the workplace is free from hazards that could cause injury or illness. This duty includes taking appropriate measures to identify and mitigate risks. Additionally, laws such as Title VII of the Civil Rights Act prohibit discrimination on the basis of race, color, religion, sex, or national origin. This means employers must actively prevent discriminatory practices in hiring, promotion, and other employment decisions to foster a fair work environment.

While offering promotions regularly, conducting annual performance reviews, and implementing a specific dress code policy can certainly be beneficial practices for an organization, they do not carry the same legal obligations under employment law as ensuring a safe workplace and preventing discrimination. These actions may be part of a company's policies and procedures but are not mandated by law in the same way that safety and anti-discrimination measures are. Therefore, the emphasis on safety and non-discrimination is a core duty that employers must uphold to comply with legal requirements and protect their employees' rights.
