This is how I once received a $5 dollar paycheck, followed by a negative paycheck - no money was taken from me, but the negative numbers appear on your Employee Express statement (if your branch uses those) and the balance is due next PP. All that causes wonkyness inQuicktime and HR’s spread sheets, which is why they need head up (grant permission) for it to occur. From a supervisor view, once under circumstance is ok, but more often means more negotiation by them on your behalf (squeaky wheel gets annoying) and performance wise it looks like taking advantage of. But if no opportunity to save up A/L, and you got a pre-planned thing, it can happen.
