Human Factors
While the loaders unloaded my plane in ZZZZ; a gust of wind blew over some boxes one of these was a Hazmat box that I had not been informed was put on my plane back in ZZZZ1.This loader and I have had problems with multiple times he'll not listen to what I want for Max loading so I have to watch him closely as well as tell him a lower number because if I look away he always goes between 50-100 over; and will wait to tell me the door weight until after he's finishes his paperwork so I have less time to do my paperwork when they finish. I've spoken to another pilot in base and they've had the same issues. I will have to be even more diligent when he loads my plane. I have informed the chief pilot of this issue.Recommend this company develop should a similiar paper to other freight operators that states if they are or are not loading Hazmat. That way in case the Hazmat is put in a bag or hidden behind a larger box I would be able to say this is missing.
Captain reported undeclared Hazmat cargo discovered during unloading at destination.
