I've worked or I've been working?

Hi, Julio!

I studied about this yesterday. You use the first answer when it happened just in the past. When you use I HAVE WORKED it's like (Eu já trabalhei aqui em tal período). So, you can't say "I have worked here SINCE November 2000".
I think the correct is saying "I have been worked here since November 2000". Cuz you began to work in the past and it continues in the present.

If you watch the Gavin's videos about Present Perfect and Present Perfect Continous, you will get it better.

Hi there, The correct answer is "I've been working here since November 2000"
You have to use "present perfect continuous" because your working wherever you work It's an action that started in the past I mean in "November 2000" and it is still in action till this very day that's why you have to use "present perfect continuous". Hope i helped

Hey Julio!

Firstly I wanna thank you for your precious contribution to the Forum!

Now let's take a glance at the topic:

Present Perfect Simple x Present Perfect Continuous

Both tenses are used to express that an action began in the past and is still going on or has just finished. In many cases, both forms are correct, but there is often a difference in meaning. It depends on what you wanna emphasize.

Mainly we use the Present Perfect Simple to express that an action is completed or to emphasize the result.

On the other hand, we use the Present Perfect Continuous to emphasize the duration or continuous course of an action.

Eg.
I have done my homework. (Meaning: My homework is completed now.)
I'm wet because I've just washed my car. (Being wet is a result of the previous action)

I have been doing my homework. (Meaning: That's how I have spent my time. It does not matter whether the homework is completed now.)

You also have to consider if this action is permanent or temporary.
If an action is still going on and we want to express that it is a permanent situation, we would usually use the Present Perfect Simple.

For temporary situations, we would prefer the Present Perfect Continuous.

PS: This is not a rule, however, only a tendency.

Eg.
James has lived in this town for 10 years. (Meaning: He is a permanent resident of this town.)

James has been living here for a year. (Meaning: This situation is only temporary. Maybe he is an exchange student and only here for one or two years.)


Now, back to your question, do you wanna express the result or duration of this action? Of course duration since the question focused on that (how long..?)

But is it temporary ou permanent?
I guess permanent!

So, my friend, I'd say that both are correct! Grammatically speaking!

I'd prefer to use the Present Perfect Continuous though! Because it is the same verb tense used in the question and it is an action that started in the past and is still going on.

Hope I have helped you somehow!
