Corey talks about the importance of attendance-related discipline in the grievance process. He points out the low success rate of the union as well as the difficulty of these cases, suggesting they are often won or modified in arbitration. He encourages shop stewards to challenge the validity of any "official discussion" claimed by management, as a formal discussion is required for minor offenses, and to ensure the carrier is fully aware of their attendance record and attendance reviews (or lack thereof). It is important to consult with the carrier before an investigative interview, and Corey mentions how to handle management and acknowledging management responsibilities. He also emphasizes the need to be assertive and fight for the carrier, understanding that they might be going through a difficult personal situation.
