As noted, life isn't fair. I once had a tractor the 5th wheel broke on. I dropped a set of heavy trailers just before pulling onto the road. One of the terminal employees affirmed to the supervisor I had checked visually to make sure it was properly latched. I wrote the tractor up for a 5th wheel repair and grabbed another. A mechanic checked it, said it was fine and the next day a guy from another terminal hooked a set of trailers to it and was fired for dropping them by his boss. The third day, a driver from that terminal hooked up a van to it, to make his city deliveries and dropped that trailer. He was not fired. I was not fired. The guy in the middle, did not have a boss that trusted him and valued him, he also may not have completed the proper checks like I and the the last driver.
