My manager has formed a grudge against me and basically portrayed me as having done nothing all of last year. He's also gone behind my back and hired a replacement for me. The reason that he's given to the Management is that I don't have technical skills when that is not the case and a couple of other BS reasons. To wit, the current role does not require significant technical skills (I'm fairly technical and have an engineering background but this is a non-technical role to a large extent)
I'm now trying to move out of my current company and actively looking for new jobs.
A common question that is asked is why do you want to leave your current company (For context, my company has a very good external reputation and is considered a "unicorn"). How should I answer this?
While I don't want to speak negatively about my current organization which is, for most parts, a great place to work in; most of the interview tips and prep that I've read mention that it is bad form and a bad idea to talk negatively about one's current manager as well, especially for the role that I'm in.
(Apologies for a fair amount of obfuscation and generic-ness but I know my manager is on Stackoverflow and I don't want this to be public)
Edit: I understand why it is not a good idea to bad-mouth an employer and as I mentioned in my original post, I don't want to either. I have a problem with my direct manager but I don't want to air dirty laundry
