You don't have a clue.
If fedex was screwing with him, they would never have approved buyers. In fact, they may have already lined up someone they wanted- a cousin, or nephew, or son-in-law who needed a job.
I had buyers pending approval, and as soon as they had completed all the paperwork, fedex claimed I had violated the contract by saying I couldn't 'take all these friend*ing boxes ' that another contractor couldn't fit in his truck. Supposedly, that was enough in their eyes to claim 'improper decorum' even though I was in a warehouse where people said much worse. Fedex left those buyers hanging, expecting to go to work, until the paperwork went through approving cancelling my contract. Funny thing is that the manager was fired within a couple months, and two of the three drivers they split my routes among were also fired They ended up with 4 drivers covering the area I was covering with 3, because I was able to flex packages, and knew my areas like the back of my hand. I had spent years learning the backroads and vaguries of the areas. things like addresses out of order, roads that didn't go through, shortcuts that could save hours of driving, etc.
I had 100% service for multiple years, never missed a bonus, and was always willing to help out during peak, until fedex decided that because I hired an extra driver, and had an extra van, that the area I covered at peak rates was then mine to cover permanently after peak. But the one 'christian' manager, who asked me during a ride-a-long if I believed in Christ, took a huge dislike to me on a personal level, and made up in his mind that I had to go.
After all was said and done, I ended up with more in my pocket than I would have netted from the sale, but it took a while longer. Point is that fedex is the one that doesn't respect the contract unless it suits them, and all it takes is one manager to make idiots think it is always the contractor who isn't capable when things go wrong.
