I think if you read both the article and the interview, there was an investigation conducted. But keep in mind this is a workplace, and certain rules apply. Many court battles have been fought in the US about where the employer's right to investigate employees ends and the employee's right to privacy begins. And what is he to take as true: the anonymous complaints made to a consultant by dancers (many of whom may have an agenda, given that Hubbe has raised standards since he arrived and introduced a NYCB-level of accountability and discipline to the corps in particular); or identified responses made to direct questioning? The RDB has had a well-established support system for dancers, and those who have problems are given both the resources and the time to remedy them. This is by no means a cut-throat company. So is the answer to abandon that in favor of a "let us search your dressing room" and "fill the cup" sort of regime? This is a dance company here, not Wal-Mart. There must be a high level of trust or the dancers won't grow and take chances as artists.
And yes, I was thinking of Keillor's Norwegian Bachelor Farmers even as I was typing my post . . .
