I was fired for misconduct. Unable to prove that I didn't do something, has meant that my 20 year career is over.
Once the investigation started, I had just started making plans for a new career and so I resigned. They accepted my resignation, but then told me the investigation would continue. They also changed my four week notice to eight weeks at this point. It dragged on horribly, until they finally sacked me, the day before my notice period ended.
At this point, I had been training for my new career for five weeks, but felt I had to tell them what happened. They asked me to leave the course, a) because of what I "did" and b) because I hadn't told them previously. I didn't think I needed to, as it was all still ongoing. I told them as soon as I definitely knew what was happening. I apologised for this but they still told me they didn't want me.
I desperately need to work as soon as possible but now I feel like no one will accept me again. I don't know who/where/how to try to find something.
