Working with women

I am young single male in my early 20s. I find myself working in an organization department comprised only of female staff. The other departments have male staff, but not mines. I am the only male in my work environment. I have to communicate to the young staff and and elderly staff for administration purposes and work purposes. The staff comprises of young and elderly Muslim women. I experience great difficultly in respect of understanding my role and duty as a Muslim. How do I relate to the young girls and women. Sometime they feel I am being funny when I try not to talk or make salaam to them and they make my task difficult for me. Should I continue in this job or look for another one? How should I conduct myself with the Muslim women?
