I've quit a lot of times and as a courtesy I give them a one week notice. In the past, like when I first started, I parked the truck at a terminal, went inside to operations and told them you can have your truck back. No drama or anything about it. Oh sure, they act like they cared and wanted to know why, but that's all lip service on their part.
I've even quit under load before, but parked the equipment at one of their yards, and they put me down as not eligible for rehire and then they hired me a few years later.
The bottom line is that this job is "at will" employment unless you are under contract. Either party can quit without notice or reason. The days of common courtesy are over and have been for a long time.
