Time and a half
Time and a half is a multiplier of 1.5 applied to qualifying time worked, so each such hour is recognised as one and a half. Four qualifying hours become six under the multiplier. The term describes the ratio only. It does not say which hours qualify.
The phrase is arithmetic wearing a jacket. One and a half, applied to a quantity of time.
Two things it does not tell you. It does not say which hours qualify; that comes from a policy or from local rules. And it does not say what the recognition consists of. Some employers apply the multiplier to time off instead.
Related multipliers follow the same shape. Double time is a factor of two.
The phrase also travels badly. It is common in some countries and almost unknown in others. Elsewhere the same idea appears under another name, or not at all. So a policy copied between places can describe something nobody there recognises. Say what qualifies and what follows, in plain words.

PeopleMuster supplies the underlying record: which shift a person was on, when they clocked in and out, and how many hours resulted. The multiplier comes from the employer's policy.
Questions people ask
What does time and a half mean exactly?
A factor of 1.5 applied to qualifying time. Two hours count as three under that multiplier. Which hours qualify is a separate question with a local answer.
Is time and a half automatic for weekend work?
No. Nothing about a weekend triggers a multiplier by itself. The qualifying conditions come from your employer's policy and the rules where the work happens.
How do you calculate it?
Multiply the qualifying quantity by 1.5. Six qualifying hours give nine. The arithmetic is the easy half. Deciding what qualifies is the hard half.
