I'm suck in a rut and not sure what to do...any advice here is welcome!
I have a full time job, Mon-Fri, 9-5 working as a IT Tester in a company that I have been working for for about 4.5 years (5 years in Oct

)
I earn £20k per year atm...
My problem is this...I have worked in 7 departments whilst I have been here - either in a permeate roll or as cover for peak periods etc.
I landed my current role by fluke...i have no idea what i am doing most of the time (despite working in IT for over 12 months now) from a technical stand point and the guy who i work with is just awful...he hordes all the work load, takes what little work I do manage to do off me.
They have recently employed another member of staff to work in our testing team (now 3 of us) who has no company back ground experience OR and IT qualification's or testing experience of any sort and he is being paid a lot more than me (I think we are of similar age too)
I am so unhappy in this work role...I was happier in my last position (I was a staff Trainer here and loved it) but the money was awful and i basically took this IT position for the money and experience and 99% of the time I am doing NOTHING from day to day and i hate it.
I have spoken to my office manager, and he said that they are looking to re-structure the department so they can put me in a position where I have my own work load and responsibilities, but that was 4 months ago and nothing has changed yet...
My thoughts are this:
A: Start looking for a new job
B: Stick it out and hope it gets better
Problem with option A is that I have no 'on paper' qualifications or experience in using industry recognised systems or programs - this whole business is ran on in house software or bespoke systems. Also whilst I was working in training (the role i really loved) I enquired about the company paying for me and the other trainers to go on a recognised trainers course but they refused it. So short of kicking everything out of the box and going to Uni at 27 years old, I'm screwed there
Option B all hinges up on how long I can hold out with the job being the way it is at the moment, before it changes for the better OR they fire me for just generally being ****....
I DONT KNOW WHAT TO DO!!!!!!!
