After I was out of the bullying situation and had time to reflect I learned :
To trust my gut . If someone feels off they usually are.
To grey rock and avoid eye contact.
To nip it in the bud straight away , people will do to you what they think they can get away with .
In some cases kill them with kindness . It's hard to be mean to someone who is being nice to you , especially in front of others .
Some bullying esp in the workplace is actually a deflection, by putting attention on you it detracts from them.
In the case of some workplace bullies it's just best to cut your losses and move on . Some people are in so thick with management you will never win and they have done a character assassination on you anyway .
The most important thing to remember is if it wasn't you it would be someone else . The problem lies with the bully . Never blame yourself or think you have something wrong with you .
A bully relies on silence . Speak up always .
