Hello. I can assist you with your question.
Have you recently (last several months or year) been under additional pressure?
People that are in positions to do so have disagreed with you, maybe even giving you some type of verbal and even written corrective actions?
Please let me know at any time if I'm way off. I'm speaking from intuition.
I sense that you have been doing some work on something that may threaten the other teachers - or some of them.
Something that you are doing or are part of to help improve the school and the quality of the teachers through some standards around performance.
There are a couple of female superiors that are not involved in the back-biting - "above the fray" so to speak. Both females. At least one is in a very high position and is familiar with your work. Either one or both of them think highly of your work, and in general all the negative stuff - even though there's more of it, doesn't matter. Complaints and or write/ups in your case are a product of the insecurities of others. I hope this makes more sense to you than it does to me!
So, what you are undergoing now is temporary and may be a result of you taking the initiative to make the school system better through a project or projects. I think your troubles are behind you. If you have moved from one school to another, leave the past where it is and continue what you are doing. I see you raising up above all the noise soon - within the next 6-8 months.
At that point, I don't think you would be worried about which classrooms you will be teaching or who likes you and doesn't. At that point, the work you have done will have provided the validation you needed to have the confidence to step up in your career at the request of someone higher, perhaps a director, maybe administering some sort of improvement program starting on a local level and expanding down the road. You are doing good stuff. Focus on that. Focus on what administrators like to see from you and pay little or no attention to any feedback you receive from those (especially union teachers) that may be impacted by your projects to insure the schools have certain objective standards for teachers. In principle, you are right and doing the right thing.
That's about all the detail I have for you now.
Hopefully it's good enough news to encourage a huge bonus!
You are going to do fine... but don't let your expectations and speculations clutter things... just do what you are doing and don't worry about the rest.
Wow, this was a great reading: you have hit a lot of issues right on target. Is it possible for me to schedule an appointment with you so we can chat online?
