One place I worked posted a statement in our coat room, bathrooms and such. Can't remember the exact words now,but it is something that every single person should ponder.
The management of any org./ business/club that operates with honesty, integrity, fairness and consideration,will have a staff or members that reflect same. A leadership of integrity can not long operate according to the standards they profess without those standards being reflected by those with less responsibility.
By the same standards a staff with integrity, fairness,honesty, and consideration can not co-exist efficiently with a leadership that provides less. In time, one will change and be guilty of that which they rail against.
Another place I worked sent in a behavior specialist to problem solve some things that seemed to be beyond management.
There was blatant workplace bullying. He had rather a simple concept and one that was very efficient in solving the problem. A general meeting and then one on one.
"It is not enough to claim you don't like something". A bully exists or unpleasent circumstances continue, because those that don't like it fail to say NO.
Each one involved was given a simple remedy. When the very first sign presents itself, Say No, I am not going allow you to do this. The leader of the bullying pack is only as strong as those surrounding him are willing to let him be.
Without them, the taunting,cruelty,abuse cease. It needs an audience and praise to let it thrive. Once the power to do so is lost ,so is the leader
