Will going around the Scheduler's back hurt his prospects with his current MSC because people really hate it when you go to a higher level of management or accounting. I've seen it only end up badly, its something you use only when your prepared not participate in any more shops with this MSC. I am no newbie, been doing Retail Consulting since 1981, accounting, auditing, marketing, advertising and forensic in-depth audits looking for fraud. When I was a manager I got hammered for going above my DM's back but I was prepared for all the backlash because he was about to cost our retail chain "hundreds of thousands of dollars with his stealing and sexual harassment". The sad part was the company did not realize I was helping them, they thought I should go through the DM who was stealing and harassing my female employees.
The DM did not get fired, he came back to me asking "Why did you go around my back?" later on when lawsuits started piling up the company wanted me to lie about contacting them about his conduct which I had fully documented and recorded. What do you think I did?
