Decades ago, I worked in a warehouse. There were two major sections...I worked on the side where we pulled and packed data sheets, manuals, brochures and such for our clients. The other side was "Mechanical," where they did bulk mailings.
This amounted to two completely different sets of alpha males (very few women worked in the company at the time, mostly in a separate hand-insert department...that changed in the years that followed).
The "Mechanical" guys were hard-drinking folks. They had a SEPARATE refrigerator for beer only. That's right, folks...in the mid-to-late 70s, you could operate heavy-duty mass mailing machinery with a cigarette hanging out of your mouth and a Coors at your fingertips.
The guys on my side were more of a stoner crowd. We drank a little here and there, but we were sons of the herb.
We were East and West, North and South...we didn't particularly care for them, they didn't particularly care for us.
The company's owner had the brilliant decision to shift one of the managers from the Mechanical department to manager of our department.
On day 1, he walked us through the department and pointed out all of the things that displeased him, and capped one of his rants off with "I will not tolerate this."
We all silently looked back and forth at each other, but rest assured...it was a mass solidarity "kiss my ASS" moment.
We did everything we could from that moment on to undermine, circumvent, ignore and generally screw with this guy in ways so subtle that he never felt the sting until the scorpion was miles away.
And, within a couple of months, he realized he had no control over his department, and that it really wasn't his department at all...he was just sort of visiting. So he pulled us all into a room, fell on his sword, apologized for being a dick and asked us to work with him. And from that day on, we did.
He was actually a decent, funny guy underneath it all...he was simply a hardass, and he learned that a hardass wasn't going to play in a group of guys who had elevated THC levels in their systems and just wanted to peacefully pack their boxes for eight hours a day and go home.
A few years after that, I had received several promotions, and he was in a different department as well. I used to kid around with him mercilessly and he took it all with a sly "screw you" grin. I used to love to look at him and say "I will not tolerate this," and he got the joke.
But Trump's not like that, and Kelly going public with his displeasure...either directly or via the observations of friends and associates...is only going to encourage Trump to "assert his authority" and become an even bigger dick.
