A duty of care is a legal obligation that is imposed on an individual or organization to take reasonable measures to protect the safety and well-being of others. This duty is owed to anyone who may be affected by the actions or inactions of the individual or organization.

For example, a doctor has a duty of care to their patients to provide an appropriate standard of care and treatment. This means that the doctor must take reasonable steps to diagnose and treat the patient's medical condition, and must act in the patient's best interests. If the doctor fails to meet this duty of care and the patient is injured as a result, the doctor may be held liable for medical negligence.

Similarly, a company has a duty of care to its employees to ensure that the workplace is safe and free from hazards. This means that the company must take reasonable steps to assess and manage risks, and must provide appropriate training and protective equipment to employees. If the company fails to meet this duty of care and an employee is injured or becomes ill as a result, the company may be held liable for a breach of duty.

The duty of care also extends to the general public. For example, a property owner has a duty of care to ensure that their property is safe for visitors. This means that the property owner must take reasonable steps to identify and fix any hazards, such as broken steps or loose railings. If the property owner fails to meet this duty of care and a visitor is injured as a result, the property owner may be held liable for a breach of duty.

In summary, the duty of care is a legal obligation that requires individuals and organizations to take reasonable measures to protect the safety and well-being of others. This duty is owed to anyone who may be affected by the actions or inactions of the individual or organization, and failure to meet this duty can result in legal liability.
