Final answer:
The best way for HR to fulfill its duty of care is by scheduling a walk-through during a work shift and consulting with managers and supervisors about new hazards in addition to reviewing revised floor plans with insurers in compliance with OSHA regulations.
Step-by-step explanation:
To best fulfill its duty of care to employees after an assembly operation has redesigned its work floor and added new machines, HR should use a comprehensive approach. Scheduling a walk-through of the redesigned area during a work shift allows for real-time identification of potential hazards and immediate feedback from employees on any concerns they may have with the changes.
Furthermore, considering OSHA regulations that emphasize employers must find and correct safety and health problems, consulting with affected managers and supervisors about new hazards is also a key step as they have day-to-day site knowledge that can be instrumental in assessing risk. Lastly, integrating the revised floor plans with the organization's insurers can also be part of the due diligence process to ensure that all changes meet safety standards and that coverage is appropriate for the new operations layout.
