When you’re writing about jobs, schedules, or describing work arrangements, you might pause and wonder: Should I write “full time” or “full-time”?
It seems like a tiny dash, but that hyphen changes everything. Choosing the right form matters if you want to maintain writing clarity and professionalism, especially in business communication, job applications, or any context involving employment terminology.
What’s the Issue with “Full Time” vs. “Full-Time”?

The confusion often arises because both “full time” and “full-time” are seen in writing, sometimes interchangeably. But they’re not the same in terms of grammatical structure.
The choice depends on how the word is being used in the sentence. Is it a noun or an adjective? Let’s dig into that.
The Correct Usage According to Grammar Experts
Grammar authorities like The Chicago Manual of Style, AP Stylebook, and Merriam-Webster agree:
- Use “full-time” when you’re using it as an adjective before a noun.
- Use “full time” when you’re using it as a noun or adverb.
✅ Correct: She has a full-time job.
✅ Correct: He works full time at the firm.
❌ Incorrect: She works full-time at the firm.
❌ Incorrect: He has a full time job.
This rule follows a broader grammar principle called the correct grammatical usage of compound words specifically compound adjectives.
Noun vs. Adjective: Why It Matters
Understanding noun vs adjective difference is crucial when deciding whether to use a hyphen.
- Noun/Adverb: When “full time” describes the duration someone works (“He works full time”), there’s no need for a hyphen.
- Adjective: When “full-time” comes before a noun (“a full-time employee”), it should be hyphenated.
This rule falls under the broader topic of grammar rules for compound modifiers.
Hyphen Usage and Compound Modifiers
Let’s look at a basic rule in English writing style:
Use a hyphen when two or more words work together as a single adjective before a noun.
That’s called a compound modifier. For example:
- A well-written article (not “well written article”)
- A high-speed train (not “high speed train”)
- A full-time position (not “full time position”)
This is the core of proper hyphen usage.
Real-World Examples: Emails, HR Documents, and More

📄 Internal Memo: Incorrect vs Correct
❌ Incorrect: All employees working full-time must submit reports by Friday.
✅ Correct: All employees working full time must submit reports by Friday.
This sentence uses “working” as the verb, so “full time” is functioning as an adverb. No hyphen needed.
Why “Fulltime” is Almost Always Wrong

Let’s address the elephant in the room.
“Fulltime” without a space or hyphen? That’s not grammatically correct in formal writing.
While you might see it on job boards or in casual writing, it’s not accepted in professional writing or editing guidelines. Standard dictionaries like Merriam-Webster and Oxford list “full-time” (hyphenated) as the correct form.
So if you’re searching “fulltime or full-time“—go with full-time every time.
Grammar tip: “Fulltime” may appear in URL slugs or SEO contexts, but it’s not correct for formal documents.
Understanding the Full-Time Employment Definition
Let’s zoom out and look at what full-time employment actually means.
Full-time employment definition:
A job requiring a person to work the standard hours typically recognized by a business or industry, often between 35 to 40 hours per week.
This type of employment typically includes:
- A regular schedule (e.g., 9–5)
- Health benefits
- Paid leave
- A complete schedule over a full working week
Knowing this helps you use the phrase more accurately.
Full Time vs Part Time: A Quick Comparison
Criteria | Full-Time | Part-Time |
---|---|---|
Hours per week | 35–40+ | Typically <35 |
Benefits | Often included | Often excluded |
Job Security | Higher | Lower |

This topic is popular in employment types, and helps distinguish phrases like full-time job vs part-time job.
