How do I get my w2 online from labor ready in Dayton, Ohio?

They should have given you info on retriving it online. If this is part of the national company, I believe they do.

But you must contact their office. If you moved since you last worked there, most likely they mailed it. Or information about it, to the last address you had on file.

Labor Ready sounds like a temp agency. Your W2 should have been received on or before Jan 31. You contact their offices for info on how to get it.
