It is a hard line to walk, about self-expression or your job. Like others have said in this forum, you have to pick your battles wisely. However, maybe after discusing it with your employer and the company, check with a lawyer and see what your rights are. This is no different than people that are Jewish wearing a yamulke to school on Passover. It depends on how much noise you want to make about it, but you have to see how far you are willing to go, and what sacrifices you are willing to make.

I admire your courage and conviction.

Best of luck with everything
