This is always a management issue. If the so-called lazy persons are not your management then You should be having a discussion with management about them, though I would still make great effort to not make it trash talk. You should make sure your hard work is being recognized and compensated for.

Of course, if the lazy persons are management, then the job itself was doomed. Remember that most people quit managers, not jobs.

I am not saying you should stick around, just keep this in mind for the next round of employment.
