Here is one of them: Diala Ghneim, Communications Manager.
Canary Mission has a page on her and says that she has supported terrorists on Facebook (she took down that link) and is/was a member of the “F**k Israel" Facebook group.
Ghneim was also a student activist with Students for Justice in Palestine (SJP) at Rutgers University.
Her current Facebook page show that she "likes" the BDS movement and many anti-Israel groups.
A typical Facebook post claims that Jesus was a Palestinian with the type of propaganda we would expect at UNRWA schools.
UNRWA-USA doesn't have the same neutrality requirements that UNRWA has, as it is not a UN agency. So the hate and lies can be freely shared, as we've seen many times in the past.
