This past year I have had to train a lot of people as 7 people in my team left the organisation due to bad management. I have had to train a lot of new people. I have not had any tasks removed from my workload so my work is always in a backlog and I am not paid any extra to train people. I understand people need to be trained but disgusted the organisation just left me me to pick up the pieces when they should have brought trainers in from the software company.
I have trained the people well and saved the organisation but feel burnt out. I don't want to train anyone else up now. I have an annual appraisal. I don't know how to diplomatically express this as I have worked hard but it was not acceptable to burden me with this responsibility on top of my job.
