While I have no direct experience in CA, in every state with which I do have experience, you would take the temporary job; you would tell the state that you were working for those two weeks, and you would reopen your claim at the end of the two weeks. It would not disqualify you; in fact, at least in my state it can extend your claim. It might take a little longer than usual for the first check after your claim is reopened, but taking the temp job cannot hurt you and may help you.
