Where do I go from here?

What I put in bold is right from your words. I'm not saying you were wrong to leave. I would have done so as well. I'm on your side here. My point is why inflame the issue when it's better to just come up with a BS reason to leave and go cool off. Right or wrong, words said in anger have a tendency some times to boomerang back at you square in the teeth. I applaud your moral stance on telling the truth. In this situation, you left a ticking time bomb and it went off.

About a year ago I was helping a guy get on with a Richmond Virginia based carrier. This was after almost engaging in a fistfight with a shop manager his then carrier used. based on my information the shop manager was in the wrong. Instead of just leaving this guy started bad-mouthing the shop, made some disrespectful comments about the girl in the office, then promptly was called by his boss and fired. I have tried to counsel this person about their anger issues. Hopefully, they will not lose this job.

In your case, while you might not want to admit it, you set somebody off and they no longer wanted to deal with you. Hey, a few years before I retired I had a young smartarse on a dock to remove my trailer brake air before I could disengage the system so he could place a lock on the gladhand. I got out of my truck and told that guy if he ever puts his hands on my truck again I would bury my fist down his throat! I was hot and had a legit reason to be. Yes, I got called by the account manager that handled that account. The conversation was pleasant, and after a few days of cooling off, I apologized to this account manager. There are times in almost every occupation when you get angry. If you need to cool off go cool off. I don't consider it to be dishonest to disengage from a situation by coming up with a BS reason. I'm done, I do wish the best of luck going forward, oh and you were NOT wrong to get angry!

 

Does the new dozer operator screw everybody over
By not digging the hole deep enough or just you.
Seems to me all the drivers that unload there
Should have been complaining about him.
Not just you.

 

I was also thinking that same thing. This was why I said it's better to go cool off. It could be that many other drivers are angry. It might also be the case this actually happened but another driver did it. This sounds like a bad problem way beyond the OPs actions.

 

He said it to 30 to 45 minutes longer to unload.
If that's every truck, then the dozer operators boss
Should have been on his ### long before the truck
Drivers did.
That's a couple loads short every day.

 

Communication is so important. Getting angry and lashing out is not communicating when EITHER party does it. Chances are this person is dealing with his bosses, the constraints of their job as well as other truckers. I do think this can be saved, I just am not sure the OP can do it right now.

If a driver goes to the same places all the time, over time you start to develop casual friendships. The reverse can also be true. I won't say what Walmart DC it was, but there was one DC that had a traffic clerk that hated my company. Gave me the stink eyes when I was in there. I always noticed I seemed to be in that door forever. One day I was waiting and was getting close to hitting my 14-hour limit. I asked her why she was so angry with my company. She told me one of our drivers called her names one day and got so belligerent security removed him. That driver was fired when the people that handled General Mills freight said that driver was no longer allowed in GMs property and had been banned in that DC. I know this because I asked later. Because I hauled a lot of candy I almost always had some Hershey or Mars stuff in my truck. I asked that girl if I could make it up to her. I got 2 boxes of those display boxes and gave them to her. I never had an issue in that DC when she was working traffic.

Like @REO6205 said, communication is so important!
