The added olive on the shit pizza here is that skilled maintenance personnel, at least where I am, are a fairly small trade, and word gets around. I’ve never heard of “official” blackballing, but we ticketed folks gossip pretty readily about industry employers, and are in high demand.

Moves like that will guarantee that they can’t get experienced tradies, and even if they do, the ones that are willing to go to their next shutdown will be keeping an eye out for trouble, and at the slightest sign of bullshit and will probably cackle with glee while screwing with this employer.

Beware the phrase “I can retire anytime.”
