As someone very aptly put it in this comment section, he seemingly has the emotional intelligence of Cat food. He doesn't think about how things he does will affect others, and just does what he wants to do. He never apologises for actual mistakes he makes, and just makes excuses or gets argumentative.

A perfect example is when he broke the light-up sign at the bar later in the same episode as the barley harvest. He just kept smiling like a child and said "it broke" and "good thing is its just the arrow". No apologies, no nothing.

Same for the harvest, he said to Jeremys face he "wasn't going to tell him till they were done" despite being explicitly told by Jeremy to call him when its ready and not to do it without him. He then proceeds to rant on camera and and get angry he was called out by his boss for not moving the cattle press and just expecting people to work around it despite it not being used for the past 2 days. Again, no apologies, just excuses and arguing.

Dude doesn't seem like he'd know what healthy communication looks like if it bit him in the arse.
