Even Christians who don't talk a lot about their faith can be targeted by unfair treatment.
If there are two or three Christians at work, and one notices that another seems to be being unfairly called out for a mistake that others make, she or he may want to consider approaching the supervisor about it with the other Christian colleague to see if some sort of bias is involved.
Another reason for promoting greater Christian unification is because people in places like work or school will treat a Christian differently even if that individual doesn't talk much about their faith to classmates or coworkers. Some people feel offended by Christian ideas and this can cause them to consider actions such as undermining a Christian's work performance or socially harming them at school.
For example, people at work who feel offended or angered by Christian ideas may report common mistakes to supervisors while exaggerating them. At school, classmates who feel offended by Christianity may spread rumors about a Christian classmate and say that she or he should be stayed away from. This is why it helps for Christians to watch out for each other.

Non-Christian colleagues and classmates who pick up on situations like these are also asked to help. Christians who try to build ties with other Christian coworkers or classmates and also try to strengthen the overall unity of their Christian brothers and sisters through respectful activism help protect each other from being unfairly picked on.
