Which of the following statements is true regarding implied terms from legislation for employers?

The statement regarding implied terms from legislation for employers that is true is that employers must ensure good health and safety of employees. This obligation stems from various health and safety laws that require employers to provide a safe working environment. These laws are designed to protect employees from physical harm and to ensure that workplaces meet certain safety standards.

Employers have a legal responsibility to evaluate risks, implement safety measures, provide training, and ensure that employees are aware of potential hazards while performing their duties. Failure to comply with these legal obligations can lead to serious consequences, including legal action and financial penalties.

The other statements, while they may reflect common practices or expectations in certain industries, do not represent universally applicable legal obligations. For example, paid vacation and insurance coverage are typically dictated by company policy or employment contracts rather than by law, and promotions are based on performance and organizational needs rather than being a guaranteed requirement. Therefore, the requirement for ensuring good health and safety is the only one that is explicitly mandated by legislation, making it the correct answer.
