Prosecutors thrive on fear and intimidation to drive the results they need (often keeping things out of a courtroom). It sounds like he runs his business like a prosecutor. I've worked for someone like this where every meeting felt like a deposition, and it's totally demoralizing.
Also, as a former prosecutor, I found it telling that not only did he think jury duty wasn't worthwhile enough to let someone use their PTO for it, but he actually suspended the person without pay who even brought up the idea.
