I did an opera last year with a small company who put their singers up in host housing. One of our singers had to be moved when his host left town for a few days and did not want him there in her absence. It turns out that he was trolling for sex partners on the internet and bringing them to his host's home for, um, quick encounters. She objected to this, and the company had to find new quarters for him. They wound up putting him in a hotel, at added expense to an already slim budget. Needless to say, he won't be hired back at that company.
I just got the cast list for my next show with a different company, and this singer's name is on it. This is a company I've worked with before, so I know the people there. The question is, do I tell them what I know of this singer's problem elsewhere? If I do, am I forewarning them and heading off a potential problem, or am I spreading tales needlessly? If I don't, am I at risk of causing the company problems which could have been, if not avoided, at least anticipated?
If this were a question of professional behavior I would have no problem warning them up-front of what I know. If it were purely personal behavior it would obviously be none of my business. But what about personal behavior which could affect the company, even if it's in an area which is not part of my responsibilities?
Your advice, and especially your experiences with analogous situations, would be welcome.
Thanks.
