Often in unemployment proceedings, the hearing officer will consider all evidence present. But, the hearing officer will give less evidentiary weight to a document you say you did not receive and which the employer cannot prove (i.e. signature) you received. Additionally, at hearing, you will have an opportunity to ask questions of the employer. You should use the time to discredit the forms they are now submitting: Was the offense serios that you claim to have written me up for? If it was so serious, why didn't you have me sign the form?

If the employer states that you refused to sign then ask why he did not get a witness to affirm your refusal to sign and receipt of the warning?
