Time-and-a-half is a wage payment made to an employee at 1.5 times the normal hourly rate. This pay level is typically used when a person is working overtime, on a weekend, or on a public holiday. The circumstances under which time-and-a-half is paid should be detailed in the corporate employee manual, and should follow the mandates of the applicable government's wage laws.
As an example of time-and-a-half, an employee works a 50-hour week, and earns a standard hourly rate of $20. Since the 50 hours is 10 hours beyond the threshold at which overtime applies, the person will be paid at a time-and-a-half rate of $30 for those 10 hours.
