What should managers monitor prior to the start of shift to ensure correct headcount?

Monitoring Voluntary Extra Time or Voluntary Time Off is crucial for managers to ensure the correct headcount prior to the start of a shift. By tracking which employees have opted for extra time or have taken time off, managers can accurately predict and plan for staff availability. This practice not only helps in managing workloads but also prevents understaffing or overstaffing, which can disrupt operations and impact productivity.

Additionally, understanding employee attendance allows managers to adjust their schedules, allocate tasks appropriately, and ensure that all necessary roles are filled to maintain efficiency. This proactive approach enhances overall team performance and helps in maintaining the smooth running of operations.

Other options like employee feedback, safety protocols, and equipment readiness are essential for different managerial functions but do not directly relate to ensuring accurate headcount. While these elements are important for creating a positive and safe work environment, they do not address the immediate staffing needs that are essential for operational continuity.
