Three years ago you wrote in this forum complaining about basically the same issues. At that time
you said something about how the management was relocating you to another place. I wonder, are you in the same job, or a different one? How odd that three years later, people are still being abusive towards you.
You were given a lot of really good advice back then, so to refresh your memory, Im pasting the link below for you so you can re-read.
Being nice and bringing in cookies, etc., may indeed be the higher ground, but if you are somewhere in a large city with hardened people, this will not work as it should ideally. It will only raise their level of contempt. You need to strike a balance of not responding in the same nasty way as them, while maintaining your dignity. I wonder if you react visibly hurt or annoyed and if this is what's encouraging these people to violate you?
Here's those old but excellent responses to your old post:
I just went and read some of your old threads regarding this work situation that keeps repeating in your life. Someone else said perhaps you ought to react by being nice and bringing cookies, or whatever. I unwisely rejected that idea and suggested that may not work in a really tough crowd. I sincerely apologize to the other poster and to you for my lapse in judgement.
Here is what I found you wrote to another poster for advice in a similar situation. I have no words to describe what I think of this:
""Also if you are comfortable try to be friends with these people (it has to be a front) and beat to their game. Poison them with their own medicine. For example if there are two people who are against you but are not so close to each other, find out dirt about those two and tell each of them what the other is saying wrong about each other. They will not like it and eventually they will quit. But you must be two steps ahead of them and comfortable in doing so. Find out where they work and find some dirt on them and spread some ugly stuff about them at their work place. See how they like it. Make sure they do not know who is spreading rumors about them. They will hate it.
Fight back, dear, I know these kind of meanies.
I seriously think you need to examine your own heart. Like breeds like. Read up on the Law of Attraction.
