Having a toxic person on your staff is equivalent to putting a squeeze of food coloring in a bowl of water. While it may only be one drop, the dye will certainly impact all the liquid and before long the entire contents will be colored.
If you have evidence of toxicity – through bullying, power plays, undermining others, deceit, or omission – do not pause a moment before addressing it. Even one person can taint the entire culture.
