Your Weingarten Rights mean that you have the right to be informed, in advance, of the subject matter of disciplinary interviews and you have the right to union representation at such an interview. If you are called into the office by a supervisor and you believe that you may be disciplined in that meeting, you should always ask for a union representative to be present with you. If you one is not available you have a right to request that the meeting be postponed until a representative is available.
