I've been there... When I was in France I was doing some studies where the school finds you a part-time job where you work three times a week, and you go to school twice a week. You're supposed to make projects at work, and in the end you end up with a degree and work experience. Well that's the theory, in practice I wasted 5 years of my life in jobs where I had nothing to do (4 of them), I tried three degrees and I got none (because no project at work = bad grade). I admit for the last two ones I didn't even care about school anymore because with those jobs I knew I had no chance anyway. That, plus I don't even dare calling them 'work experience' and I'm really reluctant to work again (easy there though, as I can't find a job here).
I think the worst thing is that you get used to doing nothing. So when you actually get something to do, you take your time to do it etc. It's a stupid viscious circle. Plus in the end you start wondering if it's your fault you have no work and start feeling guilty being on Internet all day.
My advice - get out as soon as you can.
