Years ago I heard a description of passive aggressive along the lines of, The person whose precise behavior you can't put a finger on, but they manage to infuriate you and others.

All workplaces harbor some these people. Congrats to JoBo, I've had a couple triumphs like that when those abusers get exposed after my complaints and others stacked up, but it was always after they caused non-ignorable damage in the workplace.

My outlook is everyone starts with 100 points (figuratively, not literally) and loses points as they demonstrate natural humanity, foibles, and weakness. When they fall below 40 (eg not giving what they're taking) it's time to assess their character and relationship.

Well, I say all that but was caught up with a partner from whom excuses for f'ing up all the time were just charming. Used me no end. Left me for a string of other savior type women of diminishing means to support him. Wound up homeless, poor guy.

Oh. That's ANOTHER characteristic...the passive aggressive are often charming. Part of a winning strategy to maximize their personal outcomes.
