It's exactly what narcissists do. Bread and butter stuff for a narc.weird power move.
Eyan has been getting worse (as predicted) when it comes to trying to emotionally upset Jo, dominate her, demean her, own her and control her.
He gets his jollies off from the above. I expect nothing less and it will worsen. It's very clever workplace bullying, imho.
If someone else was doing exactly what Eyan does, I guarantee Kaffbo would be calling it out left, right and centre.
Kaffbo has bought and paid for a membership ticket in to Eyan's narcissistic world.
