Which is NOT a responsibility of an employer regarding worker safety?

The choice identifying the responsibility that is not typically associated with employer obligations regarding worker safety is promoting social activities. Employers are legally required to ensure a safe work environment, which encompasses providing safe work systems, maintaining and ensuring safe equipment, and delivering appropriate training and supervision for employees.

Promoting social activities, while beneficial for workplace culture and employee morale, does not fall under the specific responsibilities aimed directly at ensuring worker safety. The primary focus of employer responsibilities revolves around measures that directly protect employees from hazards and risks in their work environment.
