At least how many years should labor physical checkup records be kept?

The correct answer is seven years because this duration is often mandated by labor regulations to ensure that employers maintain adequate health and safety records for their employees. Keeping physical checkup records for a minimum of seven years allows for proper documentation in case of any health-related claims or investigations that may arise in the future. This time frame aligns with various legal requirements that emphasize the importance of having readily accessible health records for monitoring occupational health and compliance with workplace safety standards.

Shorter retention periods might not provide sufficient documentation for potential claims, whereas longer periods could place unnecessary burden on record keeping without legal necessity, which is likely why those options would not be the best choices. Keeping these records for seven years strikes a balance between regulatory compliance and practical record management.
