Corporations with dress codes don't claim that everything they do is based on the bible though. JW's do.
You also say that there is no such thing as a beard policy but that religious organisations have complete authority to make rules(policy). Cake and eat it much?
The fact is that having a beard causes issues for a JW without there being any official policy or any scriptural backing. It's a cultural "law" within the JW community passed down by Rutherford, if I remember correctly. It goes against their stated aim of basing everything on scripture and it's a clear example of the man-made origins of the cult.
