Very true but those of us with years of working experience know that when a lower ranked employee makes an official complaint about a higher ranking employee, it always creates a toxic/hostile working environment for the lower ranked employee because that employee is now seen by others as being a trouble maker all because they had the audacity to complain about the actions of a senior employee. It also creates a lot of tension because other employee's who are loyal to the senior person start to take offence at having to work with the complainant.
I've been there in companies where this has actually happened and it's all been caused by senior management not getting everyone together and talking about the situation, telling ALL staff to move on, the issue is over, there is to be no tension or animosity towards anyone, your are all to get along. But senior management very rarely do this. They allow the complainant to come back to work and that's it, they are then left to their own devices. Other employee's see then come back to their work desk and start giving the 'evil eye' or the 'evil stares' or curses under their breath or whispers in groups with other employees. All with the intent to make it a difficult working environment of the complainant. Like I said, I've seen it happen, the employee resigns and the company bosses wonder why the person resigned.
The issue for Red Bull is if the complainant is not happy with the appeal outcome and decides to take the matter further because whilst the public have been given snippets of the complaint made against Horner and the investigation into the complaint, it has all been internal meaning it is confidential to the company. If the complainant were to take it to an employment tribunal, it all becomes public. Could Horner handle having everything investigated about him made public?, could Red Bull? because that is what could happen if the complainant took in their own legal counsel and decide to take the matter to an employment tribunal.
This is why I said it is not finished for Red Bull or Horner.
