Questions people ask

Is this the amount I am owed?

It is what the statutory rate produces for the hours you entered. Your contract or a collective agreement may give you more, and in many countries usually does. The statutory figure is a floor, not a ceiling.

Which pay do I put in the hourly box?

The pay one ordinary hour earns, on the base this country uses. That is not always gross pay: several countries apply the multiplier to basic wage only, so allowances are left out. The box above says which one applies here.

Does the rate change on a rest day or a public holiday?

In most countries yes, and often by a lot. Choose the kind of day above and the rate changes with it. Where a country sets no separate rate, the page says so rather than guessing one.

Do the premiums stack on top of each other?

It depends on the country, and this is where people go wrong. The Philippines multiplies them, so overtime on a public holiday is 260%, not 225%. Colombia says expressly that surcharges apply on their own and never accumulate. Read the note for your country.

Can my employer make me work overtime?

Usually only within the limits shown above, and in some countries only with your written consent. The caps are legal limits on hours, not targets. Exceeding them is a breach even where the extra hours are paid correctly.
