Hi meatloaf, welcome
Jacko has suggested one avenue and its not a "wrong" path. Your path whichever way you go is your decision. But lets look at other paths open to you. First my experience in these matters.
1988 off work from bullying for 10 months. Basically in local law enforcement and they wanted me to not enforce the law against a local politician. I objected and continued to treat him like any other citizen. Result- Severe anxiety, paranoia, heart palpitations, family suffering etc. After 10 months off work found another profession and slowly recovered. But the anxiety lasted 25 years.
Add to that 18 years as a private investigator dealing mainly in workers compensation.
What have I learned. It is great to show courage and determination. But in this world where bullying (and other things) is newly distasteful in the workplace one can go through a lot of pain, financial hardship and loss of sleep for virtually no gain. I did get a couple of pats on the back...not much else. What was taught to me by my then occupational therapist was, that the world is grey and we have to fit in it. In order to fit we must be grey ourselves not so black and white. eg A policeman at the end of his shift is returning to the police station. He sees a car speeding. He turns a blind eye. He knows he will be working for a further 45 minutes but as well, he would never get to the station to knock off because there are offences everywhere. Another one- A woman gets paid less than a man in the workplace for the same job. Does she protest ? It is widely known this unethical wage topic is wrong but will her stance at great health cost benefit her? I say no. Her best bet is to protest in other ways.
For a short time I got a security job. I was told that I get paid for 12 hours work and am expected to work for 12 hours. No official lunch break or other breaks. Toilet break..."yes be quick". Swallow a sandwich "make sure no customer sees you chewing". Do I object as I did when bullied years before? No, I planned to leave the job as soon as a better one came along. Why? Because I knew the fight wasn't worth it. You win a battle but in the modern day you don't win a war. The same people are in charge, nothing changes.
If we object to everything we risk our health and the unity of our family by constantly surrounding ourselves with the fight.
If and when it goes to a tribunal or council your witness backs off.
Life is not black and white. My views
