Who Works For Chevra Kadisha?

I know nobody working or volunteering in Jewish funerary spaces, and I wanted to ask who are the kinds of people who generally work for the Chevra Kadisha? Are they typically Orthodox, Haredi, is there an even split between men and women?

I was looking at the Chevra Kadisha website for the area in which I live, and they say that “Details of chevra kadisha services are kept in strictest confidence to respect the privacy of families.” Is this kind of sentiment common to all Chevra Kadishas?
