Phrase: I will officiate at my position for a month effective December 01st.

[Gkukreti]

Hi Folks,

I am leaving my current organization and I've to announce that I'll remain on my position for a month effective to my resignation date i.e. 12/01/2009. I am not able to frame a formal sentence, hope you guys can help?

Here's what I wrote... "...I will officiate at my position for a month effective December 01st."

Gimme some options :)
Thanks!

I will remain in my position until December 31st.
