I had a formal grievance raised against me last year, and after a stressful and botched process I was found "innocent". The case concerned serious accusations of harassment. I agreed to mediation to clear the air but it's clear our working relationship is hampered by mistrust in both sides. I had a meeting with HR who raised the idea of a meeting without prejudice to discuss a possible exit settlement. I've been in role for almost 20 years, technically have a job to retirement and they can't performance me out. How do I best play this out? I'm happy to go...for a substantial amount of money.
