If I'm not mistaken, businesses can make one of two choices about the workplace: either to ban all displays of faith, or to allow all displays of faith. There's probably some distinction for faith-based organizations, such as churches, but, in general, businesses must make the aforementioned choice. If they allow any employee to display his faith, then they must allow all employees to display any faith. Failure to do so can result in an HR/PR nightmare, including lawsuits. I'm not advocating that you openly announce to them that you're an Zevism, because they could just fire you for "unrelated reasons" (though you would still be able to fight them in court). You can suddenly claim a more mainstream faith, and the workplace is legally required to accept it (save for certain exceptions, but the burden of proof falls on the business, and not on the individual). Friends and family can call you on this sudden "conversion," but a workplace cannot make an issue of sudden conversion, even if you don't practice the orthodoxy. It's actually a great legal loophole for you. You can cherry-pick the parts that are convenient for you at the time, and ignore the rest (much like they do).
