Is It Slander To Speak Publicly About Someone Without Their Knowledge When What They Are Stating Is True And Factual But It Harms Their Job And Their Reputation?

I was an employee for the Department Of Corrections for 10 years. And was charged with a DWI and assault two years ago. I since have moved on and started my own business. I had a client question my character when they heard that an investigator was asking a recert class if they knew me and they did and he went on to show an article that only had a one sided story for them to read. They discussed me personally in the class and then I started getting calls from ex co workers and clients.
