Dame Janet Smith, a retired judge spent nearly three years examining BBC presenter Jimmy Savile’s activities at the BBC. She interviewed nearly 500 witnesses and concluded that the “monstrous behaviour” of Savile had been allowed to go undetected for decades, because staff were unwilling to complain, for fear of damaging their careers, and that such attitudes still persisted today.

The BBC Trust has published in full the report. You can find it following this link.

Worth mentioning is one of the documents addressing the BBC's history, ethos and management culturewhere the management culture is described on page 156 as follows:

... the ‘refer upwards’ rule of management will work well only if managers actually do take their problems to the next level. It will not work well if, for one reason or another, they decide to keep things to themselves. One reason why a manager might not take an issue to the next level is that he wishes to retain, consolidate or even expand his power base. Some witnesses described departments as ‘fiefdoms’ or ‘baronies’. If a manager enjoys that kind of power, he might be unwilling to share it. I have the impression that this could have been a problem in the Light Entertainment Department in the 1970s and 1980s, where managers were strong personalities, wielding their power with confidence.
