Workplace bullying can be challenging to accept and address.
Bullying and harassment can be subtle but this does not mean you should not make a record of the time, date, and witnesses.
At any instance, if there is harassment or bullying deemed as acceptable try and raise this complaint informally if possible by raising this with your manager without delay and if the harassment or bullying is from your manager then you will most likely need a more formal route raising the grievance with their manager or the company human resources department.
Do Not Fall For The Positive Reinforcement Perception Deception
Gaslighting can happen to anyone and from anyone at work from your colleagues to management. Gaslighting is a common form of manipulation used to gain a psychological upper hand to make an individual have self-doubt.
Do not second guess yourself.
Once a manipulator at work has acknowledged that you may have had enough of their behaviour and are willing to take action they may throw in some positive reinforcements such as compliments out of nowhere after consistent negative reinforcements such as guilt-tripping, undermining and micromanaging.
Ensure you make a written record or diary of any event you deem to be unusual or makes you feel uncomfortable such as bullying, manipulation, and harassment.
Keep evidence such as emails and relevant documentation that can support your case securely in a safe place.
