With family issues your CP can take you off a trip which will automatically backfill those days with your vacation days to be awarded under the next cycle. Before the end of that month you have the option ask for these days to not be used or instead use floated vacation you had made available. This is something I have used in the past though recently there has been an “uptick” in occurrences requiring me to dig a hole into future vacation days. In the end it is still about money as bills still need to be paid even if daddy can’t work.
