The issue is their entire careers.
There was a quote from someone who said that the whistleblowers are seen as the problem and are treated accordingly.
They are disciplined (as in this case), they can be suspended or they can be 'managed out'
Many doctors (including consultants), who have blown the whistle trying to highlight malpractice have lost the support of their employers, who are responsible for appraisals and revalidation thereby losing any chance of working anywhere else
Whistleblowers were driven out at Stafford, where surgeons ended up attempting to feed and look after patients themselves trying to keep them alive after surgery and there have been multiple cardiology issues across the UK
All the whistleblowers were ignored, suspended or fired
Vindication after trials, inquests and inquiries is very often too little, too late

They want to raise the issues, they really do, but their attempts are seen as professional jealousy, with managers preferring to believe that it's all glorified office politics
IF they go straight to the police, without going through the 'proper' channels first, they are fired.
If they go to the media, they are fired and reported to their respective colleges and the BMC
They are watching people suffer, but trying to make management understand what's going on is like trying to kick a boulder into action.
