I have been working in this business for over 20 years and I have encountered people that are just pure evil. I have seen people being fired from shows unfairly due to "artistic differences" coming out of the blue, and the next day being replaced by the best friend or the new (secret) lover of the (musical) director. When the actor in question tried to ask why there never was a conversation or explanation about this he got shut down and all he heard was "artistic differences". I know he did his track wonderfully and there was never any indication or reason for differences.
I have seen a person being worked out of a show because the assistant director did not like a certain cast member who did not reply to his personal avances. When the real director was on holidays he made something up (that the actor hadn't shown up for an extra rehearsal but he deliberately did not inform that actor about this rehearsal) and he was let go and never got a chance to speak to the real director again.
Another person I know was fired due to "artistic differences" because he came in early for rehearsal one day and walked in on the musical director screwing one of the ensemble girls in the backstage area. The girl just got promoted to understudy for the lead (remarkable, as she was clearly not up to the job), and my friend who was in an ensemble track was out of work. This was a case of losing face. This was really sad too, because the actor had nowhere to go, the production company replied with "the director said artistic differences so we believe him" and "these things happen" without going into detail. Initially the actor was discrete about what he had seen. Later, the casting director of the show asked him what had happened, as he could not think of any reason why he was let go, after the extensive audition process, and when he told the story he urged him to keep it quiet, because people wouldn't believe him and it will give him a bad reputation. He really stood with his back against the wall.
Another example I encountered was more like the Loeffelholz case, where a baritone actor had been rehearsing an ensemble track with baritone harmonies for 6 weeks, it was near opening night and suddenly the MD came up to him and they wanted him to do all the tenor parts instead of the baritone harmonies. Completely different keys and out of his range. He then was forced to join the pianist, who played his new melody lines/harmonies, and then he had to sing them on his own, in front of the whole cast and directors etc. When he couldn't reach the notes (which they knew he couldn't), they made him do it 6 times too. It was very embarrassing. Later that day he was called to the office, where only the MD sat, and told him he had to leave the production. The next morning, the MD brought in a boy (who lived with him, while he was much younger), to replace him and here it comes, the boy just sang the baritone parts too. He rehearsed in private with the MD (supposedly due to the short notice of opening night) and in 3 days he just joined the whole group, so nobody noticed which harmonies he actually sang.
But I have also seen people being very mean and really putting effort in hurting someone's career just because they didn't like a person or sometimes when they were jealous.
It really is difficult because it seems that there's nothing that can be done about these situations. It's human nature and people have personal preferences, interests, fears, desires and it results in misusing power.
I know it happens everywhere but especially in the arts. I don't think it is a reason to commit suicide but it can really sweep someone off his feet. I have seen it happen too often to ignore.
