They would have to try pretty hard to create a public performance in a workplace. Public performances need to be accessible to the public without any sort of signup or invite, and just the act of being an employee means you have an invite/signup.

Well you'd be surprised. Where I live we have this semi governmental entity that collects fees for music played in the workplace and they will happily use a set of speakers connected to a computer as proof that music has been performed publicly. It's totally nuts but they have a lot of power here.
