I am not an important person in this company. I'm just a lowly cog in the machine.

My comments:

Cogs are essential parts of a machine. They’re wheels that work together to make machinery work their magic. Without cogs, machines and indeed the whole modern day industry would grind to a halt, or fail to grind at all. And so it is curious that cogs are considered unimportant.

And perhaps not so curious. Cogs are considered unimportant because they’re commonplace – in an assembly line, for instance, there are thousands and thousands of them.

Hence, and therefore, people who work mundane routines in an organization or business call themselves cogs.

And a lower cog is a low-ranking member on the staff.
