I have a slightly odd job, there are hardly any people in the UK that actually do it. It's a support worker role in a sense but quite specific. Anyhow, no-one ever seems to know what I do despite me constantly telling them in the hospital 
Consequently, I keep getting jobs dumped onto me are are absolutely nothing to do with my role that basically either no-one else wants to do or has no time to do.
I have been trying to expand the service and now my "proper" job needs to take precedence. Yesterday, really was the last straw though. I'd already told my line manager that they had to take one of the big jobs away as it's eating up 30-40% of my time. However, yesterday, I got an email saying I had to create 118 letters for patients. Last time this job was dumped on me, I had 50 and it took 3 hours so you can imagine how long this will take.
The part I am so annoyed about is when I said to my line manager that unfortunately I wouldn't be able to help on this occasion. She replied with "I think we need to work things out so that the patients are not disadvantaged" I.e DO THE LETTERS 
Well what about my patients, won't they be disadvantaged if I'm so bogged down in other people's work. Apparently there is a meeting with some of the managers next week to discuss this but I'm not holding out much hope. I am being made to feel as though I'm pitting them out when in actual fact, they have been putting me out for 9 months as I haven't been able to give my patients my full attention. Really, they need to employ someone else, maybe three days a week, to do the jobs I have been given.
Sorry rant over. Bloody NHS.
