Without giving too much away...
I recently started a new job, it's entry level, quite poorly paid. The job description was about three pages long and I read this very carefully before starting.
After starting they told me I would be expected to do something that was not mentioned on the job description. This particular task is quite daunting for me, and I have to say if I knew about it before I probably wouldn't have taken the job.
I haven't had to do this task yet, but one manager has expressed concerns that I may not be able to do it. If I cant they will almost certainly sack me.
I feel like I'm such a disappointment because I can't do it, but is it totally me fault if it wasn't on the JD? Is it worth me raising this at all?
