I don’t think he even needs a reason to have long hair. If he’s a good teacher, what does the length of his hair matter? I’m female, do I have to have long hair? If I have cancer and I’m bald, will I be suspended? If I just decide to shave it all off, will I be suspended? If you’re black, do you have to have a white hairstyle? As long as it’s clean and doesn’t interfer with your job, how you wear your hair is your own business. Children should be exposed to people of differnet ethnicities, nationalities, religions. And all of these different cultures have different standards and we should not mandate teachers into a strict white American model. JMO.
