I work for a big company, and I have been responsible for a successful project. I faced bullying, harassement and ultimately nepotism - once the project was confirmed to be successful, somebody tried to push me out of the picture, removing me from my own project. If I stay, I won't be able to get credit for my work, despite my peers and my customers recognising my contribution. I also know the same person who pushed to take over my project is pushing for my termination.
A competitor offered me more money, a more senior title and a better environment (I know quite a few people and we like each other).
My employer is planning to enforce the non-compete clause in the UK. I know that I need a lawyer, yes. But I am also wondering if there is anything done commonly in this situation. If I stay, no raise, no promotion, sidelining and possibly termination. If I leave to get raise and promotion, my employer sues me because of the non-compete clause. They don't want me to work in the company, they don't want me to work outside the company - they don't want me to exist. Is there any common practice, or something that happens frequently in these cases?
