We are a team of more than 20 people with only one woman, which is not unusual for most engineering teams.
One of the guys in our team is well known for his "unique" sense of humor, which is not technically explicit, but is often rather inappropriate if one thinks about it. But none of us had had any problem with it until we had a new female member.
The new engineer is fresh out of college but she is quite mature and her work is impressive, as we must all admit. The only problem, though, is that she is very reserved and does not take jokes very well.
On various occasions, our "class clown" would make humorous remarks/jokes targeted the new hire. She, of course, never seems amused, but unfortunately our joker never seems to notice.
One of the most "dramatic" incidents was when he said in a meeting to everyone, including people from different teams on the conference calls "Oh, Foo was being hard on Bar last night" (meaning Foo, a client, was being such a jerk, and Bar, our female engineer, had to deal with it at night, as he is in another side of the globe). But of course, not many people took it that way (and I probably don't need to say what meaning was being understood). Inevitably, a huge laughter busted out, and it lasted for sometime. Being the reserved person that she is, she did not react in any "violent" way, but she clearly looked upset with a scary stare at the engineer who made the joke.
As said, this is only one of various incidents. I am worried that it is only getting worse, and that we would come to point where we might even lose either of them.
I've tried talking casually to our male teammate about his jokes, but would get response similarly to "How else would you put it?" (implying what he said was technically correct, which is unfortunately true, and which shut me up!)
How would you deal with this situation? Do you think the joke was inappropriate? Or am I only over-reacting?
