Over
time.
This is the name given to extra play periods in some sporting events when the score is tied at the end of regulation play. Sometimes this is sudden death overtime, in which the first goal wins the game.
Overtime also refers to hours clocked by an hourly-paid employee beyond a regular schedule. Usually this means any hours more than 40 in a given week. Such overtime is usually paid at time and a half, meaning that 41st hour of work pays 1.5 times as much as the 40th.
