I'm in the state of California. From what I understand, W-2's were supposed to be in the mail no later then January 31. Even allowing for mailing time it should have arrived by now. I only worked for the employer in question, a temporary employment agency, for 2 days. They reported the income to the IRS. I've been unable to get a response so far. Several calls have been unanswered and I've gotten no response to e-mail either. How do I get these people to supply me with a w-2?
