Hello I am writing C.V. and I want to explain i am working in the factory until these times and still in the factory. So should I say " I have been working in the factory since 2006 in the field of maintenance" or should I say " i have worked in the factory in the field of maintenance " ? If i worked before in some place for example between 2003 to 2005, so should i use simple past tense ? I mean if i say " i worked in the company ZZ for 2 years " or sould i say " i had worked in the company zz 2 years " ? Thank You

If you're still working at the factory, 'have been working' is appropriate. If your referring to a previous period of employment with the factory, I'd use simple past.
