differences - Two different meanings of Present Perfect Tense

I have a problem in the interpretation of the following sentences in the present perfect tense.

1) I have worked for them since 2006.

Does it mean I am still working for them or I don't work for them any more?

2) I have lived in this house since 2006.

Does it mean I am still living in the mentioned house or I don't live in this house anymore?

EDIT: Please note that there is time expressions in both sentences.
