Hi,
Sorry, I don't know what "time-and-a-half" is? How to understand it?

Thanks

.
Time-and -a-half is the common expression for overtime or other special hourly wages that are paid to the amount of your regular hourly rate plus one-half your regular hourly rate. For instance, if your regular wages are $10 per hour, time-and-a-half is $15 per hour.

There are other premium rates (time-and-a-quarter, double time), but time-and-a-half is perhaps the most common.
