Where 240 hours shows up
Leave balances in the US are usually carried in hours rather than days, so a bank of 240 hours is a figure an HR portal will show without explaining. As elapsed clock time it is ten days. As leave it is thirty working days, because a day off consumes eight hours rather than twenty-four — six weeks of holiday, not a week and a half. Which reading applies depends entirely on whether the hours are being spent or merely passing.
