Occupational Safety and Health (OSH) is a multidisciplinary field concerned with the safety, health, and welfare of people at work.  The goals of OSH programs include: to foster a safe and healthy work environment and to protect co-workers, family members, employers, customers, and others who might be affected by the workplace environment.  In common-law jurisdictions, employers have a common law duty to take reasonable care of the safety of their employees.  All organizations have the duty to ensure that employees and any other person who may be affected by the organization's activities remain safe at all times.
