I work in learning support in a college. For the past year or so, as a team, we've been told to do tasks that are outside of our job description. There have been 3 quite extensive tasks that are going to take several hours, over the past few months. I've checked my jd and it states that "from time to time you may be asked to undertake additional tasks as requested by the principal". Well to my knowledge the extra work has not come from the principal, it's from the manager of our dept. AIBU to ask for a meeting with my line manager to say that I'd like confirmation from the principal that he has requested us to do these tasks? Or should I ask for a new jd (and higher pay to go with it for all the additional responsibilities!). I also feel out of my depth with some of the tasks due to crap (or no) training.
