I work day and night, and am governed by a queen.
She isn't always nice; she's actually quite mean.
We don't get any time off, nor do we get a lot to eat.
She always gets the food, no wonder she can't reach her feet!
We're small but oh so strong, we can lift almost anything!
Whether it be rocks or socks, or even... your great big ring.
Can you guess what I am?
