Maybe because it would be embarrising first of all.
It also dpends how someone takes it or how your boss views it. I would like to aviod that situation.
Embarrassing? Absolutely!! Job threatening? You Betcha!!
One of my jobs is/was working with kids from School groups (out on field trips) at a reconstructed Native America village, complete with the kid's parents and teachers along as chaperones. On those occasions I am teaching the kids about the early technologies and life-skills of these people, and dressed as a "Pre-European-Contact Eastern Woodlands Indian" from about 1500 AD. This means I am in tanned deerskin, breachcloth, leggings, and tunic-like top (basically "winter" attire). Measuring by shear bulk, I have on more leather than any Biker I have ever seen (The leather of the outfit alone weighs over 15 pounds). Down where my "stuf" is, the leather is three layers thick.
After one program, the front-office secretary, her supervisor (another woman), and her superviser (a man) stormed down to the village to speak to my supervisor (a woman who reports to the guy mentioned above) to report, not just to my supervisor, but to all my co-workers (six women, one guy) that one of the mothers along as chaperone had complained bitterly to the secretary that I was "showing" too much THIGH!!!! This mother was threatening to pull the school out of going to this village (thousands of dollars per year, and lost income for my co-workers as well). There ensued much public discussion about, and inspection of my outfit, my fully-concealed "stuf", and suggestions that perhaps I should be wearing a full lenght leather skirt to avoid any potential of anyone noticing that I am a guy! Another suggestion was for me to wear a double layer of bike shorts under the outfit. During this I had to stand there while my superviser sat in front of me (the whole crew as witnesses) tugging at my breachcloth and lifting it to make sure there is no possibility of anyone seeing any skin! I nearly quit over it. However, I stood my ground and refused to change my outfit (I am way-overdressed as it is!) and the incident eventually died down somewhat, although to this day there is the lingering resentment and ill-ease and nervous "joking" about it. My sarcastic suggestion was that all women entering the village had to bind their breasts with Ace bandages, and men and women had to wear monks robes to completely conceal their gender. As you can probably pick up from this rant, I am still steamed, and I no longer work there on a regular basis just to avoid the pruddie mothers.
So, DatDude has valid concerns. As has been suggested, pleated slacks, (double pleate is better, double box pleat is best), and something to protect you from "down-the-leg" syndrome like the Undergear model AO83 cotton mesh contour briefs can help. Harassment suits are fine, as long as you can find alternate employment while the suit is on-going. Otherwise, you starve.
