I'm glad to see someone here listing their PHR certification. I do have HR services listed on my site, but only those services I know very thoroughly. The problem with offering HR services is the number of laws that impact HR. You do need to have a pretty good grasp of the laws surrounding the services you offer. Getting a PHR (Professional in Human Resources) certification is a really good way to go in letting clients know of your expertise. I don't have my certification yet, but am studying to get it. Among all of the certifications out there, I think this could be one of the most important for a VA to get if she wants to offer HR services.
Go to the
SHRM website to learn more about HR certifications. What can I say, I was the Admin for a HR Director for a couple of years *grins*. Learned a lot about HR from him.
