Funnily enough, I've sort of made a 'career change' away from graphic design! I was working at a local business and even though I've not been there too long, I've really struggled financially...part-time and min wage! So I had to find full-time work, and now work as an events co-ordinator! :icon_eek: Luckily I kept up my experience/quals in a range of things and made sure I took tasks that we're transferable to many types of jobs. :icon_clapping: I'll keep my hand in graphics by taking on the occasional freelance project, just in case things change in the future, but I would say the design industry is getting fairly weak, if not already. Salaries are generally a pittance, especially for a starter/junior, competition for even the most menial & junior of jobs its almost pointless applying for them unless you know for a fact you're really upto scratch in many ways. Employers want so much from people right now, employers are dominating the job market so they will almost always pick the one with more experience over a newbie! Sorry that sounds really negative!
On a lighter note, you can always develop your skills by getting a few books/mags on layout/typography etc, you'll already have a good grounding in things like space/colour etc as fine art is an excellent subject, but you'll need to put tune creativity in a more commerical sense. The software used by most is the Adobe Creative Suite (Illustrator/Indesign/Photoshop). I personally got my last job due to being able to use Coreldraw, so I think it pays to learn as many programs as you possibly can, I've even seen a few employers demanding skills in open-source software. If you can develop any skills in web design, that'll make your position much stronger as designers these days need to be able to multi-task. I made up a few portfolio projects, which were excellent for practising and developing my software skills...this is generally okay as long as you make it a realistic commercially relevent project, and you could also try and do work for family/friends companies.
I'd also consider freelancing for a while, as this will help you get some 'real' clients, more porfolio, money (of course) and experience.
I can personally think of many ways you could be creative as a teaching assistant, even if it's during lunchtimes/afterschool clubs...how much say are you allowed to have? I would LOVE to do that kind of work!
Anyway, just take your time and practise, do it properly and don't rush it! You still have your job as security so can afford to make 'mistakes'....a job is like gold dust these days and you're lucky to be working at all! :icon_thumbup:
Good luck
