spiking
n.— «The proposed firefighter contract also would have ended a practice known as spiking, where firefighters can inflate their pension payouts. The contract was designed to limit how much overtime and compensatory time pay could be added to a firefighter’s base salary when calculating pension amounts.» —“Firefighters, City Head to Labor Court” by Tom Shaw iStockAnalyst Sept. 27, 2008.
