Stephen Warrilow www.strategies-for-managing-change.com offers these 3 strategies for dealing with toxic leadership, "if you have the misfortune of working for a boss like that."
1. Neutralize their assaults on you by never being seen to react to any of their games.
2. Always wait before responding: Toxic people thrive on the reactions that they create.
3. Respond factually, accurately, and supportively.
Warilow suggests that the "best defense for a director is to pay close and regular attention to the culture[s] within your organization."
