A health and safety policy is a focused approach toward the best practices of health and safety. Being an employer, it is important to have better knowledge of who is responsible for health and safety in the organization, when and how the operational activities bring impacts, and what actions can be taken to ensure safety and health.
If a business has a specific number of employees in its organization and is looking to imply that it cares for the workers, then it should have its own health and safety policy. You should draft the policy, share it with the respected people, and any changes/modifications should be intimated.
