I think part of the problem is that depending on the workplace, if you have traditional / Christian values, you may be the odd one out. All the time. Which no one is saying is the same as persecution and death that some Christians face, but it’s not fun to be somewhere that you feel everyone is hostile to your values and your church, and they can be downright nasty about it. I was in a work meeting once, where two different people said things like "The Catholic Church is evil. I hate the Catholic Church’, and “I don’t understand how anyone could even be Catholic” (this last statement coming from a fallen-away Catholic, whose mom had been a religious Ed teacher). My boss was sitting there, heard it, and said nothing. I can only imagine what the reaction would have been if someone had said that about another religious group, or a protected minority. But it seemed so acceptable to Catholic-bash, no one batted an eye.
