I do not have a job description as it was an internal job which it did not exist before. The difference in duties is more than just responsibility, I will do all the managing of everything including paperwork , projects and as a consequence will stall my current training to move up the ladder .
In regards to keeping quiet , of course I will not if I feel being mistreated , hence I ask for further advice.
Do you believe doing my manager's job long term in 2 occasions in the past and most likely a 3rd one now is fair?
Thank you for your advice in both posts
