Can I ask conference chair to give me an early result? I have submitted a paper in one of the top conferences in our field (IEEE Globecom 2018). Now, since this was my first time, I submitted to the symposium and now I realize that there are Workshops coming in as well. After submission of my paper, now that it is nearly 4+ months and I have written (and submitted) two journal articles. I realize the "written" quality of the Conference paper is not good and I am afraid it might get a rejection for this reason.

Can I ask the conf. chair to give me an early result so that I can submit the same paper in the Workshop with improvements?

conf (symposium) acceptance notification with come on 15th July.
Workshop submission deadline: 14th July.
You can certainly ask, but you should not expect or demand an answer. Conference organizers may have hundreds of abstracts they may need to sort through and it may not be possible to give you an answer until the notification date.
