This dude was honestly kinda insane. The most charitable interpretation is that he had a specific idea in his head of exactly how a given task should get done based on what works well for him and any employees deviating from that approach to the task are doing so incorrectly. He also did not maintain up to date documentation of any of his expected workflows so you’d better hope you remember his expected workflow when he comes to yell at you (and he yelled a lot!)

Notably he didn’t like automating any frequent tasks nor creating templates because he seemed more focused on what happens if the process goes wrong than what happens if a person makes a mistake. I would argue that humans are incredibly fallible and it’s better to have the computer automate the parts of the task that can be automated so that the human can focus on the parts that can’t be and work more quickly and efficiently, but he was far more concerned about the rare instances where the automation might break.
