I have a business idea (the business still is not set up) that I have been speaking to investors about. One of the investors it turns out knew my boss and let slip that I had met with him (lesson learnt in both speaking to my boss and trusting others).
When my boss found out he immediately called me into a meeting and fired me saying I had breached my contract and would not receive any compensation. He then told the rest of the company I was attempting to steal their ideas and set up a new business.
It's very clear to anyone knowledgeable in the area that the business idea and what the company does are very different but as they are in the same general field I decided to check with a lawyer first (before speaking to investors) that the idea would not violate my contract, which they confirmed.
I, therefore, accepted the firing, knowing that I had not breached my contract and would simply claim the appropriate compensation from the company. However, it seems my boss now has come to the realisation that indeed I was not attempting to steal the company's ideas and is backtracking on the firing.
I was never given official papers showing I had been fired but have a fair amount of evidence this event took place. I also do not want to go back to work in what would be a now hostile environment.
What is my best course of action? Am I able to quit immediately while still claiming for some sort of unfair dismissal? It is a European company.
