cog in the wheel or machine

Someone or something that is functionally necessary but of small significance or importance within a larger operation or organization. I'm tired of working in this thankless IT support job. I don't want to be just a cog in the machine anymore! Oh, I'm but a cog in the machine—it took the whole team to get this product to market so quickly. They don't care about us interns at all. We're just cogs in the machine, doing all the printing and copying without any recognition whatsoever.
