Question: how does fdny schedule work?
Answer: Firefighters normally work day shifts from 9 a.m. to 6 p.m. and night tours from 6 p.m. to 9 a.m., although it is common for them to rearrange their schedules by swapping shifts—a move known as mutuals that often results in starting at 9 a.m. and finishing 24 hours later—for personal convenience.
