Depends what is your relationship with decision makers. If you can honestly say you trust your principals- just tell them. Otherwise it probably will be difficult to turn things around without jumping ships..

I was recently close to move into management but since I have good coms with leadership I explained I will not be performing well in that role- they accepted.

I think this is the most important aspect of this. People have a lot of advice but the reality is that each company and each manager will be different and see this in a different way.

The company may have invested a lot in training, or the boss doesn't have anyone else to put in your place, or it'll be costly, or it'll have high visibility and people will start asking questions, etc, etc, etc.
