You have asked a very good question. Let me comment on your first paragraph first.
I agree with your statement, though I think there is difference in what was originally asked for when it comes to equal treatment. Women want to be paid the same as their male coworkers when they are doing the same job, with the same education, years seniority, and same quality work. To be treated equally when it comes to promotions and raises.
Now to say that men and women are equal in all aspects is just wrong. From the obvious, we don't look the same, aren't built the same. I don't want so much equality that you expect me to use a men's urinal. I am not as strong as my husband, yet I am stronger than a few men I know. Could I out work my husband in a physical job? Absolutely not. Could he do some of the jobs that I do that require a softer touch or a more technical/artisitic eye? Absolutely not. Together we make a great team though.
Now to your question. Yes, I would have been alittle upset, and depending on how this information is handled by the people who read it would determine if I felt violated or not. If nothing is mentioned of it again then no harm no foul, but if snide remarks or inuindo are made, either to me or behind my back that I catch wind of, then I would be a lot more upset. Here's why... you guys say we can see what you got, what's the big deal. I understand that, but my girls are personal, they are part of my sexuality. This is why women have tops to their bathing suits and not just bottoms like guys. I don't think you guys would like your sexuality measured and accidently put out in an email especially if you came out on the short end of the stick. Clothing and how you wear it can be your friend.
OK that's my . You asked for it you got it. Aren't you sorry you asked now?
I'm not sorry at all that I asked. In fact, I thank you for participating in the discussion. I can't find anything to disagree with about what you said. I would like to offer one point; the information in question was not gathered for any sophomoric or nefarious purpose. It was necessary information used to provide proper safety equipment for use in the performance of their duties. That does not justify making the information public or revealing it to any personnel that didn't need it. I understand the comparison to certain male measurements but IMO its not relevant. I can think of no valid reason that particular measurement would ever be needed for the job in question.
