Present Perfect Continuous

The present perfect continuous is formed with the auxiliaries have or has + been + the principle verb with ING.
Examples:

I have been working here for ten years.
He has been studying French since 1998.
They haven’t been going to class lately.

The present perfect continuous expresses the duration of activities that began in the past and continue in the present. With some action verbs (live, study, work, etc.), either the present perfect or the present perfect continuous can be used with little or no change in meaning.
Examples:
I have worked here for 10 years.
I have been working here for 10 years.
