Power Struggles in a Buddhist Group

A good friend emailed me about some troubles in a Buddhist meditation group she belongs to. It's a lay led group. The problems are some apparent power struggles about even routine matters and also an element of cliquishness. It seems to be just a small number of people out of the group that are creating the issues. I don't really know how this sort of thing should be viewed from a Buddhist point of view. But if anyone has a solution or a correct way of looking at this I'd like to pass it along to her. She likes the group overall and she really didn't expect to find this type of behavior among meditators. My specific question is "From a Buddhist point of view, how do we view bad behavior specifically in a Buddhist setting? Should we allow for these very unenlightened behaviors as we ourselves are unenlightened too? Or should be expect more and move on as this type of behavior may indicate that the meditation is this group is just not working somehow.?" In other words, if meditation is sincere and regular, can these types of defilements simply continue with no improvement in an individual?
