hi KY i suppose if the situation where you mention your interest Buddhism arises naturally, then just be natural for example, if someone asks you: "Do you celebrate Xmas, are you are Christian?" and you answer "No" and then they reply: "Do you follow any religion?" then, if you feel the situation is OK, it is only natural to reply: "I have an interest in Buddhism" or something like that but generally, in my experience, situations for discussing one's personal religion do not readily arise in the workplace, at least in Australia kind regards element
