By the end, you will never second-guess this word again. Let’s start with the short answer.

Labor or Labour Quick Answer

• Labor is the American English spelling.
• Labour is the British English spelling.

The meaning is the same. It can mean hard work, workers as a group, or the work of giving birth.

Examples:

• American: “The company needs more skilled labor.”
• British: “The company needs more skilled labour.”
• American: “Labor Day is in September.”
• Canadian: “Labour Day is in September.”

Simple rule: Pick one spelling and use it all the way through your text. Do not mix them.

The Origin of Labor or Labour

The word started in Latin. The Latin word labor meant toil, effort, or hard work. It later moved into Old French. There it was written as labour or labor. English borrowed it after the Norman Conquest in 1066.

For many years, English writers spelled it labour. Many words that came from French ended in -our. Think of colour, honour, and favour.

Then came Noah Webster. Noah Webster was an American writer who published a well-known dictionary in 1828. He aimed to simplify spelling and give American English its own identity. So he dropped the “u” in many words. Labour became labor. Colour became color.

Britain kept the older -our spelling. Today the two styles live side by side. That is why we have two correct spellings.

British English vs American English Spelling

This is not just about one word. It is a pattern. Many words that end in -our in British English end in -or in American English.

Meaning	American English	British English
Hard work	labor	labour
Hue	color	colour
Respect	honor	honour
Kindness	favor	favour
Person next door	neighbor	neighbour
Fun or joking	humor	humour
Smell	odor	odour

Words that change in the same way: labor, color, honor, favor, neighbor, humor, odor.

Words that do not follow the pattern:

• Laborious has no “u” in either style.
• Laboratory has no “u” in either style.
• Labourer keeps the “u” in British English. In American English, it is laborer.

Which Spelling Should You Use?

Think about your reader. Then choose.

Writing for a US audience? Use labor.

Writing for the UK, Ireland, or Australia? Use labour.

Writing for Canada? Use labour. Canada follows the British style for this word.

Writing for a global audience? Pick one style and stay with it. Many global brands choose American English. Others choose British English. Either is fine.

Writing for a school or company? Follow their style guide. If there is none, use the spelling common in your country.

Tip: Set your spell-check to the right language. Choose English (US) or English (UK). Your tool will then catch errors for you.

Be careful with names. Proper names keep their own spelling. The UK’s Labour Party uses “u.” The Australian Labor Party does not. US Labor Day has no “u.” Canada’s Labour Day does.

Common Mistakes with Labor or Labour

1. Mixing both spellings in one text

• Wrong: “The labor laws protect every labourer.”
• Right (US): “The labor laws protect every laborer.”
• Right (UK): “The labour laws protect every labourer.”

2. Changing a proper name

• Wrong: “Labor Party” when you mean the UK party.
• Right: “Labour Party” for the UK. “Labor Party” for Australia.

3. Adding a “u” to laborious

• Wrong: “labourious”
• Right: “laborious”

4. Thinking one spelling is wrong

• Neither is wrong. Each is right in its own region.

5. Trusting the wrong spell-check

• If your tool is set to US English, it may flag “labour.” It is not an error. Change the language setting.
