This is becoming slightly confused and ugly. The letter to the Ministry of Culture requested that they look at the theatre's finances which the artists claim are being mismanaged and are, in any case, not transparent.
The saga continues with Gergiev's reply in this article: http://lenta.ru/news/2012/11/27/gergiev/
In which he claims the letter was an emotional move that carries no weight unless a meeting has been held of all the dancers in the theatre. Because the signatories to the letter are representatives of those dancers interested in being represented, I'm not sure that's a fair statement, as I understood a meeting had been held. In any case, the letter was not emotional but factual, each claim backed up with the section of the Labor Code that is (potentially) being violated.
Например, авторы письма указывали на то, что в театре не выплачиваются пособия беременным, не ведется учет сверхурочной работы, а средства из президентского гранта распределяются между "любимчиками".
"For example the authors of the letter indicated that the theatre doesn't pay maternity leave, doesnt account for overtime (that is true, it does not) and the funds from the President's Grant are divided among the 'favorites.'"
I have been told of one case when one woman's maternity leave payments were not granted her and purposely added to another dancer's... The theatre has never paid overtime as dancers are given salaries. So someone in the theatre 12 hours per day, 6 days per week may receive the same pay and no more compensation than someone who comes for morning class plus 1 hour of rehearsal (if they have the same base rates for salary). Since there are no unions as we know them in the West, gathering the strength to fight for labor rights, to lobby for them and win (Muni in SF, anyone?) is not precedented in Russia's history.
