Here's a good one. If you are caught harrassing, pestering, annoying, bothering any employee, you are subject to termination. Because, by God, they're not going to tolerate any intolerance!
But what if your conversational style is just aggressive? What if someone is ducking your e-mails? What if someone drank your milk in the corporate fridge? You can't pester them about it? That seems awful stringent to Econo-Girl, who herself is not known for quiet stoicism. But what kind of workplace does that engender? You would be afraid for your job if you were too persistent, for fear that you were pestering. You wouldn't want to accuse your co-worker of going through your purse, for fear you were bothering her.
