Hi

I am really sorry to hear about your situation. Obviously you know your job and your boss best and therefore you need to decide whether it would be possible to have a word with your boss without upsetting the apple cart but I know a friend of mine who works in a school was also worried about people seeing her pictures on facebook etc, she arranged a formal meeting with the head and explained exactly what it was she did. She was careful not to use the word Burlesque too frequently, instead describing it as caberet, comic dance etc, she also explained that it was a character she was playing under a stage name. The head was very supportive (even though she is usually a bit of a dragon) and said that as long it was clear she was playing a part, it was fine.

I really hope you are able to find a ballance. Good luck.
