I somewhat agree with @resurgam that it's a bit of a blanket statement. It does take guts to stay through a toxic environment and try and turn it around. It also takes guts to do something new. Neither is better than the other, just what is best FOR YOU.

I would ask yourself though: if you have had a number of bad/toxic work environments, then you are becoming the independent variable in all these situations. Not saying that they aren't toxic or bad, but what are you doing that could be contributing to that or maybe having you perceived in a way that's making the environment bad for you, and what can you change about your approach in a new environment that will make it more successful? The work place never changes. All offices are toxic. It's about what you can do to bring your own positive energy, that others will follow your lead and be positive and supportive.

Please don't think I'm point a finger at you. Rather I'm just saying that we all contribute to the situations we find ourselves in. If you consistently find yourself in a toxic workplace - what is happening that's getting you there? What are you missing during your vetting of the employer?

Just some thoughts as you look for a better employer and interview them to acquire your skills and leadership.
