Im due to attend a disciplinary hearing on Thursday which I'm pretty annoyed about. Company policy is that the employee should have 3 days written notice. My boss gave me a letter late this afternoon (Tuesday). The date on the letter was Friday but I don't work Fridays and Mondays. So do I point out now that she hasn't followed procedure or just go along with the hearing and then point it out afterwards, bearing in mind that my boss is an irrational person who does not like to be corrected and will probably hold it against me forever more? Any advice very welcome.
