"Time and a half" refers to a pay rate that is 1.5 times an employee's regular hourly wage. This rate is typically applied to overtime hours, which are the hours worked beyond the standard 40 hours in a week. For example, if an employee earns $20 per hour, their overtime pay would be $30 per hour. Employers often use "time and a half" to compensate workers for the extra effort and time spent on the job. This practice is common in many industries and is regulated by labor laws, such as the Fair Labor Standards Act in the United States.
