The promise is "apologize and this will all go away". That's a lie. Never does. Depending on where you work, you may or may not be totally screwed, but apologizing when you have done nothing wrong changes bupkis.
Why give the bullies what they want? Stand your ground:
- You can cordially invite the mob to go fuck itself.
Or, for a less confrontational approach:
- You can ignore the mob and proceed as normal for a few months until they find somebody else to hate.
It's going to be a ride either way, but these bullying tactics work only because people cave. It's a trial by fire. The people that don't tend to end up more successful afterwards, and with the added benefit of knowing who their true friends really are.
A couple of important points:
- You need to commit. If you later on back down, you are done like a cheap steak. The bullies know they own you at that point. Yes, this means you might be fired, or kicked out of your university. Might get your house torched. You're going to lose "friends". Improvise, adapt, and overcome.
- These bullies want to provoke you to violence on their terms. Don't. Especially if you're the fighting type: don't take that bait. Pretty sure Sun Tzu didn't write, "Fight precisely when the enemy wants to battle."
