Had a call from my boss, and the essence was "the pipeline of work for your team is still smaller than other teams, so we need to take another body from you".
This will reduce the team to 2 UK bods and 1 Polish person. I was asked whose removal would cause least impact to the account, and I suggested mine.
Just before I suggested that, the thought formed in my head and my immediate internal conversation went along the lines of "might be amusing to suggest this in jest", however by the time the words were out, it did not seem such a bad idea. Many people have said that redundancy was the best thing that ever happened to them, and while this is not redundancy as such, it is sort of redundancy from my team, and maybe it is not such a mad thought that being moved to somewhere else, albeit that somewhere else is severely malfunctional, might be just the kick up the jacksy I need.
I think it is time to book another session with my mentor to talk discuss options.
