Short Term Disability Question

BrooklynMommy83

 I know each state and employer offer different coverage.  I was hoping someone maybe able to shed a little light for me.

I live in New York State. The state itself offers Short Term Disability, I also purchased supplemental STD through my employer.  my question is when I go on leave can I use both?

My HR department's benefit coordinator recently resigned and the HR rep I spoke to was unsure, i'm waiting for her to get back to me.  

If anyone has been in a similar situation or is familiar, I would appreciate your input.
