Grand Duke Manila (GDM), a five-star world-class hotel, hired Zoey as a banquet server. GDM informed Zoey of its company rule against tattoos as part of grooming standards. The policy prohibits hospitality staff members from having tattoos due to their different cultural meanings that might offend foreign guests. Later, GDM discovered that Zoey had an existing tattoo on her nape, which she concealed during the hiring process. After the required notices, GDM dismissed Zoey for violation of the company policy against tattoos. Is Zoey's dismissal valid? Explain. (2024 BAR)
