Bosses or Boss’s? Which One Is Correct?

Many writers pause when typing bosses or boss’s. Both look right. Both sound the same. But they mean very different things. One tiny mark the apostrophe changes the meaning completely.

People search for this because English plural and possessive rules can feel confusing. When a word already ends in -s, adding another -s or an apostrophe makes it harder. Is it plural? Is it ownership? Or both?

If you’ve ever written “My boss’s instructions” and stopped to double-check, you’re not alone. Even experienced writers get unsure.

In this guide, you’ll learn the quick answer, simple rules, key differences, and clear examples so you never mix them up again.

Bosses or Boss’s – Quick Answer

Bosses is plural.
Boss’s is singular possessive.

Simple Rule:

• Bosses = more than one boss
• Boss’s = something that belongs to one boss

Examples:

• I met all the bosses at the meeting. ✅ (plural)
• This is my boss’s office. ✅ (one boss owns the office)

If you are talking about ownership, use an apostrophe.
If you are talking about more than one person, do not use an apostrophe.

The Origin of Boss’s or Bosses

The word boss comes from the Dutch word baas, meaning master or overseer. It entered English in the 17th century in America.

English forms plurals by adding -s or -es:

• cat → cats
• bus → buses
• boss → bosses

Since boss ends in -s, we add -es to make it plural: bosses.

For possession, English uses an apostrophe:

• cat’s toy
• teacher’s book
• boss’s car

Because boss already ends in -s, we still add ’s in most modern style guides:

• boss’s decision

This is why confusion happens. You see bosses and boss’s, and both look similar.

But remember:

Plural = add -es
Possessive = add ’s

British English vs American English Spelling

American English Rule

In American English, especially under style guides like the Chicago Manual of Style and Associated Press:

• Always add ’s to singular nouns
• boss → boss’s

Example:

• My boss’s report is ready.

British English Rule

In British English, some style guides allow:

• boss’s (more common today)
• boss’ (less common, older style)
