I was planning on it anyway. Already sent a few applications in but no interviews yet. I don't know if giving notice would help at all. They sent me home today after talking to me, said they'll call me tomorrow and let me know when to come in so they can talk again, either to terminate me or discipline in some other way. I have enough saved up that I can go a few months without getting any income, and I may be able to get unemployment according to the union rep, which would help a bit.
Still not sure what to do about references.
