Hey Pandas, How Has A Negative Comment Online Affected You?

Got attacked online on a popular "rate your employer" website after I fired someone. Man I gave this guy chance after chance, gave him stime to sort his private struggles and everything, I really believed in him and put energy, time and heart in it. At the end the only possibility left was to set him free. This website is usually anonymous and it's not allowed to say names or describe people in a way they can be recognized. His post was online for about a week, before our lawyer could move them to delete it. I was so disappointed and ashamed and started to question my working-self in a destructive way. My boss had to help rebuilding my confidence. I still dont know how this shitty post could hurt me so much. But at the end it had a possitive effect, I dont care that much anymore about what people write online.
