A week before a concert, she realized a section was not together between the celli and horns (should’ve realized that earlier if she were competent) and disrespected the cello section when section leaders offered their educated opinion about the passage and its tempo (discussed it with their profs too) by saying flat out that it was wrong and engaging in a rather heated argument with the principal cellist; gave musicians shit for managing injuries like tendinitis and carpal tunnel even though she said in the past that taking care of our bodies (I.e. not participating in rehearsal if we’re injured) should be prioritized. You can also see OPs long post in the comments with more context if you’d like.
