If a prostitute is an independent contractor of a brothel and she harasses an employee of the brothel..?

Who is responsible for the actions that follow, the prostitute or the brothel? By any other standards of employment, an independent contractor is to carry liability insurance. If a prostitute threatens an employee, harasses that person into leaving, and they are now unemployed, who is responsible? A person can only lose so much dignity under the notion that the prostitute is "doing" the boss before they can no longer take anymore. Stress, embarrassment, loss of wages and the employer took no action.
