I am in a work study program in France, and I have been with a company every other month now for 3 months (and three months of school). I am studying a pretty specific subject, and my bosses have put me on a "research and development" project that has limited overlap with my studies and no clear objectives. This idea seems to have come from the top of the hierarchy, so my direct bosses don't actually have specific things they want me to do and cannot give me concrete goals or deadlines or anything (I'm basically just playing with fonts at this point).
I have spoken to them a number of times over the 3 months: first I spoke to my direct advisor in the company, he didn't have any specifics to give me and sent me to my desk. I went to see a slightly higher up boss and he said he didn't like my ungrateful tone. I have been in contact with HR and they have told me they will organize a meeting with everyone to get this straightened out. However, it's been over a week now and still nothing. I have reached a complete stand still at work (I literally have done nothing in about a month now). My school is no help either.
Is there anything I can do in this situation besides keep asking my bosses to give me things to do?
The HR person got all the different bosses who's ideas had gotten all jumbled up creating this mess and they came up with clear goals they would like me to achieve. So now I'm working on that and having this structure has completely changed my outlook on my job. Having goals means I can now celebrate achieving them, and cherish the little wins that bring me closer to the final objective. Thanks to everyone for their suggestions.
Update: Actually not a happy ending
Having now achieved the over all goal of the project, I cannot get any direction from my bosses. I have told them explicitly that I don't know what to do. I have sent them the results of my research project etc, and proposed meeting to discuss what I should do from here but I am getting no response. When I asked my boss "What should I do now", he just said "I don't know" and walked away. There was never any sort of "on boarding" process where someone actually showed me how the company works or anything, and since I've been on this solo project for 8 months now, I'm not included in any other projects and my bosses don't seem to care or want to give me things to do. This poor management seems to be going on all over the company (I've had many conversations about this with colleagues), so I'm just looking for another job now....
