We recently hired a new youth leader to our team a few months ago. She has been a believer for 6 years and seems to have zeal for her pursuit of the Lord and in time has formed great relationships with the girls in our group. Recently we had an annual indoor heated pool event for our youth group. The males are required to wear at least a tank top and the girls have to wear at least a one piece or a dark shirt over a two piece. The same rules obviously apply to the leaders. Quite to our surprise this particular leader obeyed in wearing a one piece but it was a thong in the back and extremely revealing so as to call unwanted attention and stumbling for the males and questions from the girls. She defended herself by stating she wasn't doing anything we weren't told to do which seemed like sliding by the rules because of lack of specifics. She doesn't seem to think her actions were wrong and unfortunately it seems we may have to remove her as a leader all because of this incident which will affect the girls she has already bonded with.
