Damage

Last Friday a sales was fired. She was trying her best but the company did not recognize her hard-work. Today I was called in to the CEO's office. Obviously the sales said something honest on her last day, which was not very pleasing to the bosses. My boss told me that he wants to UNDO what happened in the last three months, and to begin damage control. The damage refers to the impact on the command system in the sales team that is collapsing due to different directions inside. I was blamed for spreading negative opinions and tense relationship with sales. It can't be undone, but seems I need my damage control plan now.
