Quick Answer: Labour vs. Labor
Labor is the standard American English spelling, while labour is standard in British English and commonly used in Canada, Australia, New Zealand, and other countries that follow British spelling conventions. Both words have the same meaning and pronunciation. The correct choice depends on your audience, except when writing official names that use a specific spelling, such as the UK Labour Party or the Australian Labor Party.
The main difference between labour vs. labor is regional spelling, not meaning. If you are writing for a US audience, use labor in ordinary writing. If you are writing for a British or Canadian audience, labour is generally the preferred form.
Pronunciation: LAY-ber (/ˈleɪ.bər/). Both spellings are pronounced the same way in standard American and British English.
Part of speech: Noun and verb.
- As a noun: Labor can mean work, physical effort, a workforce, or the process of childbirth. Example: The company reduced its labor costs.
- As a verb: To labor means to work hard or move with difficulty. Example: The truck labored up the steep hill.
Labour vs. Labor: What’s the Difference at a Glance?
The following table summarizes the main differences between the two spellings.
| Feature | Labor | Labour |
|---|---|---|
| Standard usage | American English | British English |
| Meaning | Work, effort, workforce, or childbirth | Identical to labor |
| Pronunciation | LAY-ber | LAY-ber |
| Noun example | Manual labor | Manual labour |
| Verb forms | Labored, laboring | Laboured, labouring |
| Person who does the work | Laborer | Labourer |
| Common holiday name | US Labor Day | Canadian Labour Day |
| Famous political party | Australian Labor Party | UK Labour Party |
| General preference | United States | UK, Canada, Australia, New Zealand, and many other Commonwealth countries |
Neither spelling is inherently better or more correct than the other. Each follows the conventions of a particular variety of English.
Is “Labour” a Real Word or Just a Misspelling?
Yes, labour is a real English word. It is the standard spelling in British English and many other varieties of English. In American English, labor is the conventional spelling, so a US spellchecker may flag labour in ordinary writing.
The same distinction appears in other words, including color and colour, honor and honour, and favor and favour.
For example:
- American English: Hard labor can be physically demanding.
- British English: Hard labour can be physically demanding.
Both sentences are correct within their respective spelling conventions.
If you are writing an essay, business report, website article, or professional email, choose the spelling that matches your intended audience. Consistency matters more than choosing one version for every English-speaking country.
Where Did the Extra “U” Come From?
The spelling difference has historical roots. The word comes from Latin labor, meaning toil, exertion, or hardship. It entered English through French, where the spelling labour became established.
Over time, British English retained the -our ending in words such as colour, honour, favour, and labour. American English gradually adopted several shorter spellings.
Noah Webster, the American lexicographer, helped popularize these forms through his dictionaries, including his 1806 Compendious Dictionary and his 1828 American Dictionary of the English Language. He supported spelling reforms that favored simpler forms in many words.
Webster did not invent every American spelling variation. Instead, his dictionaries helped standardize and spread forms that were already appearing in print.
This history explains why American English uses labor while British English generally uses labour. The spelling difference reflects the development of regional writing conventions rather than a difference in meaning.
Which Spelling Should You Use? A Country-by-Country Guide
The correct spelling depends on the country, publication style, and audience you are writing for.
| Country or region | Preferred spelling | Example |
|---|---|---|
| United States | Labor | US Department of Labor |
| United Kingdom | Labour | Labour Party |
| Ireland | Labour | Labour movement |
| Canada | Labour | Canada Labour Code |
| Australia | Labour in general usage | Labour market |
| New Zealand | Labour | Labour Day |
| India | Labour in British-style usage | Labour laws |
| South Africa | Labour in British-style usage | Labour relations |
These are general conventions rather than absolute rules for every organization or publication. Some industries, publications, and official names follow their own established spelling.
United States
American English uses labor in standard writing. Examples include the US Department of Labor, the Bureau of Labor Statistics, and the Fair Labor Standards Act.
For US school assignments, business documents, news articles, and website content, labor is generally the correct choice.
United Kingdom and Ireland
British English generally uses labour. You will see it in expressions such as labour market, labour costs, and labour movement.
The UK Labour Party also uses this spelling in its official name.
Canada
Canadian English generally retains the -our ending, making labour the preferred spelling. Examples include the Canada Labour Code and the Canadian Labour Congress.
American spellings can appear in Canadian business and technical contexts, but labour remains the usual choice in standard Canadian writing.
Australia and New Zealand
Australian and New Zealand English generally use labour in ordinary writing. However, Australia has an important exception: the Australian Labor Party uses Labor without the u.
New Zealand also uses Labour in the official name of its Labour Party and in the name of its Labour Day holiday.
India, South Africa, and Other Commonwealth Countries
Many writers and institutions in India, South Africa, and other countries influenced by British English use labour. However, usage can vary by publication, organization, industry, and local style guide.
If you are writing for an international audience, follow the spelling convention of your main readership and use it consistently throughout the document.
When Do Americans Have to Write “Labour”?
American writers sometimes need to use labour even when the rest of their writing follows US spelling conventions. This usually happens when the word appears in an official name, a direct quotation, or the title of a work.
Proper names should retain their established spelling. Changing a name to match American spelling can create a factual error.
Examples include:
- The UK Labour Party: Retain Labour when discussing the British political party.
- The International Labour Organization: Preserve the organization’s official name.
- The Canada Labour Code: Use the official Canadian title.
- The New Zealand Labour Party: Keep the spelling used by the party.
- A quoted British document: Preserve labour when reproducing the original wording accurately.
Why Is It the Australian Labor Party but the British Labour Party?
The Australian Labor Party is a notable exception to the general Australian preference for labour. The party adopted the spelling Labor in the early twentieth century, and that form remains part of its official name.
The British Labour Party, by contrast, retains the British spelling Labour.
Therefore, an American article discussing both parties may correctly use Labor and Labour in the same paragraph. The spellings refer to different official names, so they should not be standardized into one form.
How Do You Spell Laborer, Laborious, and Laboratory?
The spelling difference between labor and labour also affects some related words, but not all words derived from the same root.
| Meaning or form | American English | British English |
|---|---|---|
| Base word | Labor | Labour |
| A person who performs labor | Laborer | Labourer |
| Past tense | Labored | Laboured |
| Present participle | Laboring | Labouring |
| Requiring considerable effort | Laborious | Laborious |
| In a laborious manner | Laboriously | Laboriously |
| A room or facility for scientific work | Laboratory | Laboratory |
The key pattern is that the u is retained in common British forms such as labourer, laboured, and labouring. However, words such as laborious, laboriously, and laboratory do not normally take that extra u in either standard variety.
For this reason, labourious and labouratory are not standard spellings.
Labour vs. Labor in Real Sentences
Seeing the two spellings in context makes the difference easier to understand. The following examples show how regional spelling conventions work in everyday writing.
Everyday Conversation
American English: “My sister has been in labor since early this morning.”
British English: “The workers put in several hours of hard labour.”
Both examples use the spelling expected in their respective varieties of English.
Business Writing
American English: “Rising labor costs affected the company’s profits.”
British English: “Rising labour costs affected the company’s profits.”
The meaning remains the same. Only the regional spelling changes.
News Writing
An American publication might write:
“The Labour Party proposed changes to employment policy, while US officials discussed the effects of rising labor costs.”
Both spellings are appropriate because Labour Party is part of an official name, while labor costs follows American English conventions.
Everyday Expressions
American English: “Building the house was a labor of love.”
British English: “Building the house was a labour of love.”
The expression means that someone does something because they care about it, rather than primarily for financial reward. The spelling follows the writer’s regional convention.
Formal and Legal Writing
American English: “The Fair Labor Standards Act establishes federal rules concerning minimum wages and overtime.
In this example, Labor is part of the law’s official title. Legal names should be reproduced accurately rather than changed to match another country’s spelling.
Common Mistakes People Make with Labor and Labour
Even though the distinction is straightforward, writers sometimes make avoidable errors.
1. Mixing American and British Spellings
Switching between labor and labour without a reason can make an article look inconsistent.
How to avoid it: Choose the spelling convention that matches your audience. For a US-focused website, use labor throughout ordinary prose.
2. Changing an Official Name
Replacing Labour Party with Labor Party when referring to the British political party changes its official name.
How to avoid it: Check the exact name of an organization, law, holiday, or political party before editing its spelling.
3. Adding a U to Every Related Word
Some writers assume that every British word related to labour must contain a u. This produces errors such as labourious and labouratory.
How to avoid it: Learn the standard spelling of each related word instead of applying the base-word rule mechanically.
4. Assuming the Words Have Different Meanings
Labor is not more formal, more modern, or more professional than labour. Neither spelling has a different meaning simply because it contains an extra letter.
How to avoid it: Focus on the regional spelling convention rather than trying to distinguish the words by definition.
5. Trusting Spellcheck Without Checking the Language Setting
A spellchecker set to English (United States) may flag labour, even when you are quoting a British organization correctly.
How to avoid it: Set the document language to match your audience, and check proper names manually.
Related Words: Labor, Work, Toil, and Effort
Although labor and labour have identical meanings, they are not always interchangeable with every related English word.
| Word | Meaning | Example |
|---|---|---|
| Labor / Labour | Work or effort, often involving physical or sustained exertion | The project required hours of labor. |
| Work | A broad term for an activity or task | She finished her work before lunch. |
| Toil | Hard, prolonged, and often tiring work | Years of toil helped build the business. |
| Workforce | The group of people available for or engaged in work | The company expanded its workforce. |
| Effort | Energy or exertion applied to achieve something | His effort improved the final result. |
| Childbirth | The process of giving birth | The hospital has a dedicated labor and delivery unit. |
The word work is broader than labor, while toil emphasizes difficulty or prolonged effort. Workforce refers to people rather than the activity itself, and effort focuses on the energy used to accomplish something.
In phrases such as organized labor, the word can also refer collectively to workers or the labor movement. The intended meaning depends on the context.
