I work in a lab and we spent all day arguing this. I said no, that bacteria are not animals and therefore not invertebrates... but those arguing the other side say they don't have vertebrae and therefore are invertebrates.

In its simplest terms, invertebrates are creatures without spinal columns (or something resembling one). So yeah, I guess you could say bacteria are invertebrates simply off of that.
But vertebrate/invertebrate is a method of breaking up different categories in the animal kingdom, not so much for categorizing bacteria.
It's like saying.. this bacterium has a cell wall. Plants have cell walls. Therefore this bacterium is a plant.

No. Bacteria are in a separate branch of the tree of life and not considered animals. Invertebrates are animals without vertebrae (spinal column, notochord, etc)

Of course they are. They have no vertebral column, and by virtue of that itself they become invertebrates. Besides, they arent even higher organisms, so the question doesnt even arise.

No, bacteria are in their own Kingdom.
