I've moved this over from Links for discussion.
A key paragraph from The Independent -- and thanks for the clarification, Brendan:
Members of the Royal Ballet in the performers' union Equity have held meetings at which they came close to passing a vote of no-confidence in Mr Stretton. Instead, they have asked union executives to raise "a number of serious concerns" over his management style with Tony Hall, executive director of the Royal Ballet's home, the Royal Opera House.
A meeting is understood to have been set for Tuesday. Neither the union nor Mr Hall would discuss in advance the matters to be raised, but sources close to the company said the dancers' main concern was over casting decisions. "There are a number of serious matters, but we want the union to tackle the way productions are cast," a source said. "There is a complete lack of information. We never know whether we will be involved in a production or when that will be.
There must be something else going on here that the dancers don't yet want made public. Casting complaints are serious, but not enough for a vote of no confidence. It will be interesting to learn what the "number of serious matters" are.
