Job, profession, post, position, career, work, occupation and trade all describe what you do for a living, but they are not interchangeable. A job is one specific paid position. A profession is a field requiring qualifications. Post and position are formal words for a job inside an organisation. A career is your whole working life. Work is the activity itself and is uncountable. An occupation is what you write on a form. A trade is a skilled manual occupation. Choosing the right one is one of the fastest ways to sound more precise in professional English.
These eight words cause more confusion than almost any other set in business English, partly because most languages cover the same ground with two or three words. Here is what separates them, at a glance:
| Word | Meaning | Countable? | Where you hear it |
|---|---|---|---|
| Job | A specific paid position, or a task | Countable | Everyday conversation |
| Profession | A skilled occupation requiring specialist training or qualifications | Countable | Formal, describing a field |
| Post / Position | A job within an organisation | Countable | Recruitment and formal writing |
| Career | The whole professional path over a working life | Countable | Interviews, long term plans |
| Work | Employment, or the activity you do as part of your job | Uncountable | Everyday conversation |
| Occupation | The regular work, profession or job you do | Countable | Forms and official documents |
| Trade | A skilled manual occupation | Countable | Skilled manual fields |
Now the detail, with examples you can use straight away.
1. Job
A specific paid position, or a task. Countable.
This is the everyday word. It covers both the role you are employed in and, more loosely, any task you have to complete. That second meaning surprises learners, but it is extremely common at home and at work.
He’s got a new job.
I’ve got a few jobs to finish at home.
This is going to be a big job.
Because job is countable, you can have one job, two jobs, or a few jobs. This is the word to reach for in normal conversation, and the one that will almost never sound wrong.
2. Profession
A skilled occupation requiring specialist training or qualifications. Countable.
A profession is a whole field, not a single role, and it carries an assumption of formal training. Medicine, law, teaching, accountancy and nursing are professions. Retail work and driving, however skilled, are usually not described this way.
What profession is Mike in?
Nursing is a respected profession.
Most jobs in the legal profession require years of hard work.
Notice the last example: jobs exist within a profession. That relationship is the clearest way to remember the difference between the two words.
3. Post and position
A job within an organisation. Formal, and used in recruitment. Countable.
These two are near synonyms and both are more formal than job. You will meet them constantly in job adverts, contracts and internal announcements, and rarely in casual conversation.
She was appointed to the post of CFO.
The position has been filled.
One practical note: post is more common in British English and in academic or public sector contexts, while position travels better internationally. If you are writing for a global audience, position is the safer choice.
4. Career
The whole professional path over a working life. Countable.
A career is the arc, not the point on it. It spans many jobs, sometimes across more than one profession, and it implies progression and direction rather than simply being employed.
A career in publishing.
Petra built a successful career in the arts.
He’s had several jobs throughout his career.
I want to build a career with this company.
That final example is worth memorising for interviews. Saying you want to build a career with a company signals long term commitment in a way that saying you want a job never does.
5. Work
Employment, or the activity you do as part of your job. Uncountable.
This is the one that catches almost every learner, because work is uncountable. You cannot have a work or two works in this sense. You have work, a lot of work, or some work.
I’ve got a lot of work to do.
What line of work are you in?
Steve’s at work today.
I have been out of work since May.
Those last three are fixed expressions worth learning whole: what line of work are you in is a natural way to ask about someone’s job, at work means physically at the workplace, and out of work means unemployed.
6. Occupation
The regular work, profession or job you do. Countable.
Occupation is the bureaucratic word. It is accurate and neutral, and it lives almost entirely on forms, in official records and in written descriptions of people.
Writing is my chosen occupation.
His current occupation is listed as accountant.
Please write your name, age, and occupation on the form.
Here is the practical warning. If someone at a networking event asks about your work, do not answer with my occupation is. It sounds like you are filling in a visa application. Say what you do instead.
7. Trade
A skilled manual occupation. Countable.
A trade requires real skill and usually an apprenticeship, but it is learned through practice rather than academic study. Electricians, plumbers, carpenters, welders and mechanics all work in trades.
Jacob learned his trade as an electrician.
What trade are you in?
There is a high demand for people entering the trades.
Note the plural in that last example. The trades, as a group, refers to skilled manual work as a whole sector, and it is the standard phrase in discussions about skills shortages and vocational training.
The mistake almost everyone makes
If you take one thing from this article, take this: work is uncountable and job is countable. They are not swappable, and mixing them up is the single most common error with this vocabulary.
- I have a lot of work to do. Correct.
- I have a work to do. Incorrect. Say a job or some work.
- She has two jobs. Correct.
- She has two works. Incorrect.
- I am looking for work. Correct. Also correct: I am looking for a job.
How to choose the right word in three seconds
In conversation you will almost always want job, work or career. The other five are more specialised. A quick guide:
- Talking about your specific role: job
- Talking about the activity or being employed at all: work
- Talking about your long term path: career
- Talking about a qualified field: profession
- Writing a job advert or a formal announcement: position, or post
- Filling in a form: occupation
- Talking about skilled manual work: trade
And when a native speaker wants to know what you do for a living, the question is almost never what is your occupation. It is what do you do? That is the one to expect, and the one to ask.
Frequently asked questions
What is the difference between a job and a career?
A job is one specific paid position. A career is your entire professional path across many jobs. You can change jobs several times within a single career.
Is work countable or uncountable in English?
Work is uncountable when it means employment or activity. You cannot say a work or two works. Use some work, a lot of work, or switch to a job.
What is the difference between a profession and a trade?
A profession requires academic training or formal qualifications, such as law or nursing. A trade is a skilled manual occupation learned largely through apprenticeship, such as plumbing or carpentry. Both are skilled.
What is the difference between post and position?
Very little in meaning. Both mean a job within an organisation and both are formal. Post is more common in British English and in public sector or academic contexts, while position is used more widely internationally.
When should I use the word occupation?
Almost only in writing, on forms and in official records. In speech it sounds bureaucratic. If someone asks what you do, name your role rather than saying my occupation is.
How do you ask someone about their job in English?
The standard question is What do you do? A slightly more casual alternative is What line of work are you in? Both are far more natural than asking about someone’s occupation or profession directly.
Key takeaways
- Work is uncountable. Job is countable. This is the error to fix first.
- A job is one role. A career is the whole path. A profession is the qualified field the job sits in.
- Post and position mean the same thing. Prefer position for an international audience.
- Occupation belongs on forms, not in conversation.
- A trade is skilled manual work, learned through apprenticeship rather than academic study.
- To ask what someone does for a living, say What do you do?
