MawBroon, it is easy for people in any workplace to "turn their backs" when witnessing a work colleague being bullied or harassed. However, those carrying out the harassment or bullying inevitability move on to another employee having forced someone to leave their employment, it never fails.
As I pointed out on this forum some weeks ago, my company investigated a severe workplace accident last year involving a young mother receiving life changing injuries after being hit by a forklift. The investigation brought forward that very serious harassment and bullying had been carried out against the forklift driver, which constituted the root cause of the accident.
Many in the workplace knew of the bullying prior to the incident happening but did nothing. The female employee will in all probability never walk again. Therefore, so much for doing nothing in the face of harassment and bullying in the workplace.
Those of us involved in the investigation were appalled at what we found, and several within the company were dismissed from their employment over the incident while others received various stages of warnings.
