Under what condition can an extended vacation of more than 4 days BUMP seniority?

The correct answer is that an extended vacation of more than 4 days can bump seniority if it is done by the end of shift with senior requests. This means that if a firefighter submits their request for vacation time in accordance with seniority rules and does so prior to the end of their shift, it allows for adequate notice and consideration of senior requests.

In many fire departments, seniority plays a crucial role in determining personnel allocation, especially for leave requests. When vacation requests are made following the established procedures, they ensure that the system respects the chain of seniority while addressing the needs of the workforce.

The other options do not align with typical seniority policies. Requests during holiday periods might be subjected to different staffing needs and may not adhere to standard procedures concerning seniority. A request from someone who has not taken any leave previously may not necessarily impact seniority rules, as the system usually prioritizes requests based on the timing and adherence to established protocols. Similarly, while family emergencies are valid reasons for leave, they do not typically allow someone to bump seniority unless they comply with the notarization or justification guidelines laid out by the department.
