You should be able to wear a hairnet and remain employed. I assume the rationale for not having long hair is to prevent hair from getting in food, maintaining a clean appearence, etc. If so, then wearing a hairnet should settle the matter.

Please post your jurisdiction and I'll see if I can find a law.
