What is the latest time by which leave must be rescinded before a shift?

The latest time by which leave must be rescinded before a shift is at 1800 hours (6 PM) the day prior to the shift off. This timing is significant as it allows for proper staffing and operational planning by ensuring that management is aware well in advance of any changes to personnel availability.

By requiring rescindment of leave by this deadline, the department can effectively manage resources and assign personnel as needed to maintain adequate coverage and safety protocols. It provides a structured timeframe that supports not only operational efficiency but also minimizes last-minute surprises that could disrupt service delivery and response capabilities.

In contrast, other times listed would not afford the same level of predictability or allow for adequate adjustments in staffing. The 1800 hour deadline is thus a balanced approach to managing leave and operational needs, promoting both individual rights to request leave while ensuring that the team's requirements are upheld.
