Why is "my father is at work again" not correct?

Question please:Mio padre è ancora al lavoro. As lavoro is "I work", why is it not "mio padre è ancora al il suo lavora" as in "his work"?

so ancora can mean more, again, still, even, and yet?

I wonder, why duolingo lists it ONLY as "even" if there are other meanings and it offers them in the exercises? Italian itself is difficult enough, do not mislead us, duolingo, please.

Not appropriately translated. It could be 'my father is not yet at work' or 'my father is still at work'

Apparently "my papa is still at work" doesn't work because your "dad" is not your "papa"? WHY DUOLINGO?!?!
