Because they are talking and intentionally harassing your daughter about her body parts, she could potentially file a claim for sexual harassment under federal discrimination laws... or a hostile work environment claim under OSHA laws.  The behavior is unacceptable, especially considering the age of your daughter.Your daughter needs to express her dissapproval of the statements to the owner so that she learns the valuable lesson of standing up for herself and knowing that their actions are inappropriate.  If this job is having a negative effect on her, she needs to quit the job and cite the harassment as the reason for her leaving.  She can then go file a state claim or federal claim for harassment.  Federal claims would either be through the EEOC or OSHA... but EEOC seems the best fit.  Even if she doesn't file the claim, learning self-advocacy for issues like this are valuable lessons for young women.Your daughter can continue working there if the two of you think she can handle the environment....that's a personal decision, not a legal decision.  However, no job is worth compromising who you are.  Your daughter seems like a young and loving spirit.  She doesn't deserve to be treated less than who she is.
