In the public sector there seems to be an extreme sensitivity to overt displays of Christ belief. I do not mean obtrusive Christianity, where an officer (I was told this story from another Dept) would bring his Bible to roll call and read it out loud whenever the meeting veered into an area he considered debauched (His career was necessarily short), but rather small personal displays of faith.
I have taken to wearing covert Christian items, that while in plain view do not trigger anti-Christian sentiment but still profess my faith. I do not really know if these things really benefit me or anyone else or, more importantly, advance the King's Kingdom, but they make me feel better. Frankly speaking in a team environment sensitivity needs to be on a forefront of everyone's mind, if I am doing what I am supposed to they already know what I believe and what I wear really should not have any bearing, so there is little use in lugging around a ten pound cross. Here are the links of a couple of items I have purchased for this purpose.
