The employee's past history is exactly why we have progressive discipline. Late once, verbal warning. Twice, written. Third, three days of LWOP. Fourth, termination. Without equal discipline, employee A can be written up for uniform non compliance, and employee B just an informal warning. Employee A leaves the rig dirty and low on fuel, gets one day LWOP. Employee B gets a warning. We all know certain individuals that have gotten on management's bad side, and the supervisors look for anything and everything to write the employee up, to create a paper trail, things they wouldn't bother anyone else for. Progressive discipline ensures that all employees are treated equally, and not by favoritism. If you've messed up twice in the past, the next one's a step three. Of course, some offenses go right to a step two, three, or four.
