Let's Kibbitz: On Jew-Dentifying Yourself at Work

[Ask Shuli is on vacation, so we’re asking you, our TC Jewfolk readers, to answer this question amongst yourselves. Nu, two Jews, three opinions, right? Let’s have it.]
You wear a kippah at shul. You put a mezuzah on your doorposts, but are you “out” as  a Jew at work? Especially as young-ish folks trying to break into corporate culture, and find our way up the ladder in a difficult economy, it seems like we should be tussling with this question. When is it okay to be Jewish at work? And how?
Do you Jew-dentify yourself at work? And how have your colleagues/superiors reacted?
