No, can express herself to her hearts content if she likes... just not where an employer has rules or standards for the business.
Damn, huge thunder and lightning blasting away right now!! Building just shook...
So what? Smelling badly does not affect a lawyer from winning a case but poor hygiene will get you understandably fired. It is perfectly reasonable for any number of reasons and one could be health and safety, one could be because of head gear that they are supposed to wear like a hat or visor at a pub and another could be simply because the employer wants them to be clean shaven or to have well groomed and visible hair.Because controlling what someone wears on their head that doesn't affect their ability to do the job isn't reasonable.
How about my monk scenario? Monk wants to wear orange robes at Subway Sandwiches instead of a Subway T-Shirt. That OK? Seems like you think it should be.
How about telling fast food worker that they do not have to wear the uniform/shirt provided? A waiter at a restaurant requiring a tie can wear a belly showing shirt?
A pretty ridiculous ruling. An employer should be able to demand that his employees do not advertise their religious beliefs on the workfloor.
