conflict resolution

My work environment is pretty void of conflicts, which makes it a very pleasant place to be in that aspect. It’s not a “real job” though as much as it is an outlet for student workers, which is where my idea for potential conflict develops. Most of my co-workers are undergrads, and they tend to not care about actually getting any work done. There is very little supervision over my area so I suppose they don’t feel the need to bust their butts in order to get stuff done. Personally, I don’t care what they do. Their work doesn’t affect my work at all, so I do my job and let them do theirs.
There could be a problem, though, were our work-loads and responsibilities to ever intertwine, not just for me, but for anyone else who feels that the work performances were unbalanced. Conflicts could arise over who is pulling their weight and who is leaving their work to be done by others.
To solve this conflict, I think the best course of action would be to address the co-worker directly, without animosity, but simply to share the concern over the work not getting done. If this doesn’t help, I would approach the person again with more force and let it be clearly known what I felt about having to pick up the slack while trying to do my own work. If the issue still doesn’t get resolved, I would for a final time approach my co-worker and let him or her know that if he or she doesn’t start doing their own work, I would be taking the problem to our supervisor. If it came to telling our supervisor about the situation, I would explain my feeling about having to pick up the slack and either ask to be given more independent work or for my co-worker to be addressed.
Personally, I hate confrontation and would be doing well to follow my own plan of action, but conflict is a real part of everyday life and requires appropriate resolution to prevent further problems among co-workers. Being a snitch is never fun, but if your quality of work suffers because of other peoples lack of effort, then I think with fair warning it is a necessary attempt at resolving the problem.
