Personal opinion is that a concise statement will do.

For example: Hello everyone. Smile Over

Too long content employees do not like will feel people very rigid, the boss will not like. After all, restaurant people need the ability to improvise, and always smile.

Unless your boss has asked you to make an introduction, then you'll have to say a little more.

Hello everyone, my name is XXX (remember not to let the interruption later call you a nickname or nickname), I hope we get along well in the future.
