I need some help to fix a career mistake that I made during the pandemic. I was very successful in a job that I loved, but it had always been stressful, mainly due to the company culture. During the pandemic, I was being bullied by an influential senior colleague and quit due to the stress of it. I found a new job and didn't speak up about why I was quitting (long story, but not a good idea to do as HR was no help, etc.).
Two years on, I desperately miss my old job. I have tried hard to make the new job as good as the old one but it is fundamentally wrong for me and I am pretty angry about how it was misrepresented, tbh. In the meantime, I suspect my name has been taken through the mud at my old job. There were a lot of rumours about why I left because I was a high performer and lots of senior people were upset about it. I think it has been positioned as me having a strop or just not being able to get on with people.
I don't want to go into the ins and outs of what happened, then or since, because it is a long story and I can only speculate about some of it. My question now is, I miss my old job massively and want to go back. How would you approach this situation if you were me? How can I get my job back given that people think I there a strop when really I left because of stress? I still won't be able to talk about the bullying, but I would be better able to deal with it now that we are no longer in the middle of a pandemic.
